"Why, Princes Gate, of course," replied Crewe cheerily. "You don't suppose that a fine-looking young man like yourself could be seen in the neighbourhood of Princes Gate without causing a flutter among feminine hearts there, do you?"

"So the servants have been talking, have they?" muttered Rolfe.

"They have and they haven't. But that's beside the point. What I want to say is that you're on the wrong track in suspecting Mrs. Holymead, and I strongly advise you to drop your inquiries if you don't want to get yourself into hot water. She's as innocent of the murder of Sir Horace Fewbanks as Birchill is, but you cannot afford to make a false shot in the case of a lady of her social standing, as you did with a criminal like Birchill."

At this rebuke Rolfe gave way to irritation.

"Look here, Mr. Crewe, I'll thank you to mind your own business," he said. "It's got nothing to do with you where I make inquiries. I'll have you remember that! I don't interfere with you, and I won't have you interfering with me."

"But I'm interfering only for your own good, man! What do you suppose I'm doing it for? I tell you you're riding for a very bad fall in suspecting Mrs. Holymead and shadowing her."

Crewe's plain words were an echo of a secret fear which Rolfe had entertained from the time his suspicions were directed towards Mrs. Holymead. But he was not going to allow Crewe to think he was alarmed.

"If I'm making inquiries about Mrs. Holymead, it's because I have ample justification for doing so," he said stiffly.

"And I tell you that you have not."

"Prove it!" exclaimed Rolfe defiantly.
