“Informed her,” Margaret corrected.
“I must admit,” said Thorndyke, “that the circumstances give colour to your inference; but we must remember that they would apply equally to a man. They certainly point to an associate of some kind. The character of that associate and the nature of the association are questions that turn on the contents of that letter that Mr. Penfield received.”
“Do you think,” asked Margaret, “that Mr. Penfield would be more confidential with you than he was with me?”
“I doubt it,” was the reply. “If the contents of that letter were of a secret nature, he will keep them to himself; and quite right, too. But I shall give him a trial all the same, and you had better let him know that you have consulted me.”
This brought the conference to an end, and shortly afterwards Margaret went on her way, now more than ever convinced that the inevitable woman was at the bottom of the mystery. For some time after she had gone Thorndyke sat with his notes before him, wrapped in profound thought and deeply interested in the problem that he was called upon to solve. He did not share Margaret’s suspicions, though he had not strongly contested them. To his experienced eye, the whole group of circumstances, with certain points which he had not thought fit to enlarge on, suggested something more sinister than a mere elopement.
There was Purcell’s behaviour, for instance. It had all the appearances of an unpremeditated flight. No preparations seemed to have been made; no attempt to wind up his affairs. His banking account was left intact, though no one but he could touch it during his lifetime. He had left or sent no letter of farewell, explanation or apology to his wife; and now that he was gone, he was maintaining a secrecy as to his whereabouts so profound that apparently he did not even dare to draw a cheque.
But even more significant was the conduct of Mr. Penfield. Taking from its envelope the mysterious letter that had come to Sennen and exploded the mine, Thorndyke spread it out and slowly read it through; and his interpretation of it now was the same as on the occasion when he heard Margaret’s epitome of it at Sennen. It was a message to Purcell through his wife, telling him that something which had been discovered was not going to be divulged. What could that something be? The answer, in general terms, seemed to be given by Penfield’s subsequent conduct. He had been absolutely uncommunicative to Margaret. Yet Margaret, as the missing man’s wife, was a proper person to receive any information that could be given. Apparently, then, the information that Penfield possessed was of a kind that could not be imparted to any one. Even its very nature could not be hinted at.
Now what kind of information could that be? The obvious inference was that the letter which had come to Penfield contained incriminating matter. That would explain everything. For if Penfield had thus stumbled on evidence of a crime, either committed or contemplated, he would have to choose between denouncing the criminal or keeping the matter to himself. But he was not entitled to keep it to himself; for, other considerations apart, this was not properly a client’s secret. It had not been communicated to him; he had discovered it by accident. He was therefore not bound to secrecy and he could not, consequently, claim a lawyer’s privilege. In short, if he had discovered a crime and chose to suppress his discovery, he was, in effect, an accessory, before or after the fact, as the case might be; and he would necessarily keep the secret because he would not dare to divulge it.
This view was strongly supported by Purcell’s conduct. The disappearance of the latter coincided exactly with the delivery of the mysterious letter to Penfield. The inference was that Purcell, having discovered his fatal mistake, and assuming that Penfield would immediately denounce him to the police, had fled instantly and was now in hiding. Purcell’s and Penfield’s conduct were both in complete agreement with this theory.
But there was a further consideration. If the contents of that letter were incriminating, they incriminated some one besides Purcell. The person for whom the letter was intended must have been a party to any unlawful proceedings referred to in it. He—or she—must, in fact, have been a confederate. Now, who could that confederate be? Some one, apparently who was unknown to Margaret, unless it might be the somewhat shadowy Mr. Levy. And that raised yet a further question: What was Purcell? How did he get his living? His wife evidently did not know, which was a striking and rather suspicious fact. He had been described as a financier. But that meant nothing. The word financier covered a multitude of sins; the question was, what sins did it cover in the present instance? And the answer to that question seemed to involve a visit of exploration to Coleman Street.
