IT WAS TEN days later that the ambassador gave a dinner to some prominent Englishman whom his country desired to honour.

It was the first day, after her experiences at Snacklit House, on which Irene had been visible at the Embassy, some physical blemishes, which had been reductive of her usual charms, having prompted an anonymous visit to a South Coast town, which it is better to leave unmentioned, owing to an experience she had there - one of the dubious consequences of anonymity - of which she thought it best that her father should not be told.

Her health, owing to the buoyant quality of her sanguine youth, had been unaffected throughout, and, when this evening came, she showed no trace of the experiences she had undergone excepting an inconspicuous scar near her left eye, and that she would have had patience to remain secluded until that should disappear would have been an extreme improbability, even apart from the event which we must not be drawn aside to observe, beyond the discreet allusion already made.

To the only guest who was audibly curious concerning the cause of the injury, she replied, with impregnable veracity, that it is always foolish to collide with open doors in the dark, and having put that enquiry so lightly aside she proceeded to enjoy herself as much as is possible to an ambassador's daughter who shares the responsibility of entertaining her father's guests.

Her right-hand neighbour at the dinner-table was a professor of economics of international reputation, and she concluded soundly that he would not be overwhelmingly interested in the knitting of jumpers, or the style of the season's hats.

On the other hand, her knowledge of economics was not sufficient to give reasonable hope that she could sustain a conversation upon them without exposing greater ignorance than a hostess prefers to show, and with this consciousness, and that of her international duty of entertaining her guest with a suitable topic of conversation, her mind naturally turned to a subject which had largely occupied it during the voluntary seclusion of the previous week. She introduced the question of the desirability of the marriage of cousins with the verbal adroitness which few men and most women have.

Its connection with economics (if any) is remote, but the old gentleman was one of those numerous specialists who, having succeeded in establishing a reputation for good crowing on their own dunghills, consider that any other should do equally well; and he was, more exceptionally, of wide interests and an unprejudiced mind.

He rose to the bait at once. He said that, like many popular beliefs, the objection to such marriages was only conditionally true. Like to unlike is the law of physical attraction, and cousins are likely but not certain to combine like qualities, both good and bad. The question, should cousins marry, is therefore incapable of absolute reply. Some should, and others should not. A minority of cousins are widely different in temperaments and physique, and, in such cases, if they should both be in good health, their unions might be particularly successful. Nothing can alter the arithmetical fact that the children of first cousins will have less than the normal number of grandparents, and the one who is duplicated may have an abnormally strong influence either, or perhaps both, for good and evil.

The learned doctor having a rather penetrating voice, which was more frequently exercised in the classroom than at the fireside, and the guests not being numerous, his remarks gained the attention of a silent table.

A discussion followed, exposing some differences of opinion, but nothing was said to disturb Irene's opinion that the learned doctor was a most able man.

Mr. Thurlow, listening without comment at the other end of the table, concluded that if Will Kindell were asked to dinner his daughter would not be vexed, and being a man of prompt action when his decisions were clearly made, he telephoned him next morning, and found, without surprise, that his invitation was promptly accepted.

Kindell came that evening, and found that the ambassador and his daughter were dining alone.

Mr. Thurlow explained that he had asked him because he was curious to know what was being done by the police to secure the conviction of Professor Blinkwell (to whom he alluded in language unfitting for the lips of an Envoy Extraordinary and Minister Plenipotentiary of the august country he represented) for his countless crimes, and he enquired with a more personal anxiety to what extent Irene was likely to be involved in the criminal proceedings which had become obviously unavoidable.

"We don't want," he said, "more publicity than we can't help, but we know the mistakes we've made, and I want Allenby to understand that there'll be no squealing from me."

"I told the superintendent that I should see you tonight," Kindell replied, "and he authorized me to say that, so far as Irene is concerned, unless you should wish to prosecute, in which case every facility will, of course, be given, it is not proposed that any action be taken.

"The men principally concerned - Snacklit and Burfoot - are accused, with Wilkes, of the more serious crime of the murder of the taxi-driver; and Snacklit has disappeared."

"They expect to apprehend him?"

"With his face in the state it is, I should say, if he has fortyeight-hours' run, he'll be an exceptionally lucky man. But if he doesn't get caught by this time tomorrow, it's an open secret that there'll be a sufficient reward offered to make it sure that someone will give him away.

"It isn't only the murder. There's no doubt that he's been up to his neck in the drug racket, and the chance of ending that is too good to miss.

"That's the common-sense view of the matter, though there's one man on it - Inspector Dunchurch - who's been arguing that we shan't find him, because it was his body of which the remains were in the furnace."

"That sound improbable. But he has some theory to support it?"

"He has the fact that when the ashes were sifted some buttons were found which bear the name of Snacklit's tailor. There'd be more in that if it hadn't been the usual procedure to give Wilkes rubbish and refuse of every kind to burn in the furnace. The most natural explanation is that some old garment had been thrown in, perhaps after it had been used as a rag."

"But it's possible it was he?"

"Possible? I suppose most things are. But it isn't sense. If it were he, it must have been either murder or suicide.

"I don't say he hadn't some motive for committing suicide, but would anyone choose such a method? And what about Blinkwell having seen him in the lounge a few minutes before? And of Wilkes being in charge of the furnace?

"And it isn't as if we didn't know that the taxi-driver had been thrown in an hour or two earlier. And who should want to murder Snacklit? It's just trying to be too clever, and substituting a wild improbability for a reasonable explanation that fits the facts like a glove."

"Well, I've nothing to say against that. There are only two things that interest me about it now. The one is whether Irene or I will be required to give evidence, and the second is what's going to happen to Blinkwell."

"We're not going to ask you to give evidence. You're clear out of it, so far as our police (or the S?ret? for that matter) are concerned. We can't avoid Irene going into the box. She's one of the most important witnesses, though you can rely on counsel and the Press - being discreet.

"But as to Blinkwell, I'm afraid I can't do more than pass on the disappointment we're all feeling. We haven't merely decided that we can do nothing ourselves We've been almost down on our knees begging Paris to look at it in the same way.

"We don't think any magistrate would make an extradition order on Gustav's word, which is the only real evidence they've got. And, for ourselves, we don't feel that we've got sufficient to make a case against him on the drug-smuggling issue. We should be just asking for trouble.

"We may be able to look at it rather differently when we've got Snacklit. He'll probably talk, in an effort to get himself out of the mess. But, even then there's the same difficulty as with Gustav. It's just a criminal's word, and not much use without better confirmation.

"Still I should say that, if we catch Snacklit, we shall soon have the Professor in the same place. Otherwise not. But you can say it's a hundred to one that we'll get him, one way or other, though we may have to go round by another road."

Mr. Thurlow was satisfied by the explanation. He thought that Snacklit was unlikely to elude pursuit, which he knew to be a much more difficult enterprise in England than in his own more spacious and (in some respects) more primitive land. He thought therefore, that Professor Blinkwell's remaining days of liberty would not be long.

We may observe the soundness of the Professor's judgment when he used his foot, with such economy of effort, to put Snacklit in his appropriate place.

As to what did happen to Professor Blinkwell, which exemplified the familiar proverb that the pitcher which goes often to the well will get broken at last - that is another story, and must be told at another time.

But it may be recorded here that both Burfoot and Wilkes were convicted and duly hanged. Wilkes, in a last effort to dodge the rope, did tell his solicitors of the manner of Snacklit's end, which those gentlemen communicated to the police, who, without considering Wilkes to be a mirror of exact truth, were inclined to credit it, and the promotion of Inspector Dunchurch, which shortly followed, may have been partly due to this confirmation of the theory to which he had held so stubbornly. But it was decided that it would be impossible to prosecute Professor Blinkwell on the unsupported evidence of a convicted murderer, and Wilkes' anticipation that he would be kept alive to give that testimony proved to be a mistake.

Irene gave evidence, which the Press treated with that voluntary discretion which is the usual consequence of a word from Whitehall or Downing Street, and that she was the daughter of the American Ambassador was not generally known. . . . The Press of the United States, under banner headlines, had more to say; but it was fortunately of the right kind.

Mr. Thurlow, outlining these future events with considerable accuracy in his astute political mind, was feeling content with the world and with those around him. He would have liked to have continued the conversation after coffee was served. But he was a discreet man, and one who knew when silence or withdrawal are positive rather than negative actions. He said that he had matters of urgency with which to deal in his own room.

Irene and her cousin were left alone; and it is obvious that there is no means of knowing what took place afterwards, beyond disclosures which either of them made, which were not of a detailed kind. But much may be inferred from an announcement in The Times which Myra read at breakfast only two mornings later.

"A marriage has been arranged - - "

She laid down the paper, looked at her uncle, started to speak, and checked herself. Her rather heavy features resumed their usual immobility. But it cannot be recorded that she looked pleased.

As to Professor Blinkwell, he took no notice at all. His mind had strayed erratically to the moment when he had struck a blow from behind at a man's neck hard enough to make silence certain, and from such an angle that there would be little risk of any bloodstain resulting upon a dinner-jacket which it would have been a pity to spoil.

THE END
