“Undoubtedly,” agreed Thorndyke. “There is no greater folly than to take failure for granted and reject an opportunity. Now, if this plan of yours should by any chance succeed, Mrs. Purcell’s emancipation is as good as accomplished.”

“Is it really?” Varney exclaimed, eagerly.

“Certainly,” replied Thorndyke. “That is, if Purcell should send a letter the contents of which should disclose a state of affairs which would entitle his wife to a divorce. But that is too much to hope for unless Purcell also would like to have the marriage dissolved.”

“I think it quite possible that he would, you know,” said Varney. “He must have had strong reasons for going off in this way, and we know what those strong reasons usually amount to. But would a simple letter, without any witnesses, be sufficient to satisfy the court?”

“Undoubtedly,” replied Thorndyke. “A properly attested letter is good evidence enough. It is just a question of what it contains. Let us suppose that we have a suitable letter. Then our procedure is perfectly simple. We produce it in court and it is read and put in evidence. We say to the judge: Here is a letter from the respondent to the petitioner—or her solicitor, as the case may be. It is in answer to an advertisement also read and put in evidence; the handwriting has been examined by the petitioner, by her solicitor and by the respondent’s banker and each of them swears that the writing and the signature are those of the respondent. In that letter the respondent clearly and definitely states that he has left his wife for good; that under no circumstances will he ever return to her; that he refuses hereafter to contribute to her support, and that he has transferred his affections to another woman who is now living with him as his wife. On that evidence I think we should have no difficulty in obtaining a decree.”

Varney listened eagerly. He would have liked to make a few notes, but that would hardly do, though Thorndyke seemed to be a singularly simple-minded and confiding man. And he was amazingly easy to pump.

“I don’t suppose Purcell would give himself away to that extent,” he remarked, “unless he was really keen on a divorce.”

“It is extremely unlikely in any case,” Thorndyke agreed. “But we have to bear in mind that if he writes at all, it will be with the object of stating his intentions as to the future and making his position clear. I shall draft the advertisement in such a way as to elicit this information, if possible. If he is not prepared to furnish the information, he will not reply. If he replies it will be because, for his own purposes, he is willing to furnish the information.”

“Yes, that is true. So that he may really give more information than one might expect. I wonder if he will write. What do you think?”

“It is mere speculation,” replied Thorndyke. “But if I hadn’t some hopes of his writing, I shouldn’t be at the trouble of putting in the advertisement. But perhaps Rodney is right; I may be unreasonably optimistic.”
