The Vanishing Man

"If he went to his brother's house after his visit to Hurst, the disappearance is more understandable if we don't mind flinging accusations of murder about rather casually; for the disposal of the body would be much less difficult in that case. Apparently no one saw him enter the house, and, if he did enter, it was by a back gate which communicated with the library--a separate building some distance from the house. In that case it would have been physically possible for the Bellinghams to have made away with him. There was plenty of time to dispose of the body unobserved--temporarily, at any rate. Nobody had seen him come to the house, and nobody knew that he was there--if he was there; and apparently no search was made either at the time or afterwards. In fact, if it could be shown that the missing man ever left Hurst's house alive, or that he was wearing the scarab when he arrived there, things would look rather fishy for the Bellinghams--for, of course, the girl must have been in it if the father was. But there's the crux: there is no proof that the man ever did leave Hurst's house alive. And if he didn't--but there! as I said at first, whichever turning you take, you find that it ends in a blind alley."

"A lame ending to a masterly exposition," was Thorndyke's comment.

"I know," said Jervis. "But what would you have? There are quite a number of possible solutions, and one of them must be the true one. But how are we to judge which it is? I maintain that until we know something of the parties and the financial and other interests involved we have no data."

"There," said Thorndyke, "I disagree with you entirely. I maintain that we have ample data. You say that we have no means of judging which of the various possible solutions is the true one; but I think that if you will read the report carefully and thoughtfully you will find that the facts now known to us point clearly to one explanation, and one only. It may not be the true explanation, and I don't suppose it is. But we are now dealing with the matter speculatively, academically, and I contend that our data yield a definite conclusion. What do you say, Berkeley?"

"I say that it is time for me to be off; the evening consultations begin at half-past six."

"Well," said Thorndyke, "don't let us keep you from your duties, with poor Barnard currant-picking in the Grecian Isles. But come in and see us again. Drop in when you like, after your work is done. You won't be in our way even if we are busy, which we very seldom are after eight o'clock."
