"Yes, of course. They've all got important information, and they all want to see me personally—or else the Commissioner. Well, where is he, Shapton? Show him in."
"I can't. He's gone, sir. He'd been waiting here half an hour or so when he was taken away by Sir Ralph Fairfield."
If he had not been trained to school his feelings, Heldon Foyle might have started. As it was, he picked up a pen and toyed idly with it. The man, who had a fair idea that his news was of importance, was a little disappointed.
"I see," said the superintendent. "What happened?"
"Why, Sir Ralph asked to see you and was shown into the waiting-room with the other man. They both seemed a bit upset, and the first chap's jaw dropped. 'So you are here,' says Sir Ralph, a bit angrily. 'Yes, sir,' says the other, and he had become sulky. 'This is my man,' says Sir Ralph to me, 'and I would like a word with him alone, if you don't mind.' Of course, I left 'em alone. In a quarter of an hour they came out, and Sir Ralph told me that there had been a little misunderstanding—that neither of them wished to see you after all."
"Thank you, Shapton," said the superintendent, resting his chin on his hand. "Ask Mr. Green if he can spare a moment, will you?"
In the interval that elapsed before the chief inspector came, Foyle did some quick thinking. Criminal investigation is always full of unexpected developments,
and this seemed to him to offer possibilities. It was clear to him that a man had come to Scotland Yard to give some information, and that Fairfield had followed post-haste to shut the man's mouth. For the moment he put aside all speculation as to the baronet's motive. The question was, who was the man he had taken away? Who would be likely to know something? It must be some one intimately associated with the baronet, some one who probably lived with him. There was only one man—his servant.
The line of reasoning became clear. What would a servant know which he would recognise as of obvious importance? Fairfield might have received a letter from Grell, but if he did not wish to let the police know of it, he would scarcely have been careless enough to leave it where his man might have obtained access to it. The second solution was more probable. Suppose Grell had paid a visit to Fairfield and the man had recognised him?
Foyle was not led away by theories. He knew that the most ingenious deductions often led to failure. But in this case he had nothing to lose by putting the matter to the test. He had not taken off his hat or coat, and when Green came in he was ready to put his plan into execution. In a few words he told what had happened and his conclusions.
