He perceived intuitively that if the detectives found the driver of the taxi which brought him from the theater it was possible the man might have noticed Forbes, who had certainly been scrutinized a few minutes later by a policeman, so he hastened to add:
"You said 'any one in particular.' I did see a tall, well-dressed gentleman at the corner of the street, but there is nothing remarkable in that."
"Which way was he heading?"
"In this direction."
"Then it is conceivable that he might be the man who called on Mrs. Lester?"
"Yes."
"Aren't you pretty sure he was the man?"
Theydon permitted himself to look astonished.
"I?" he said. "How can I be sure? If you mean that, judging from the interval of time between my seeing him at the corner and the sound of footsteps on the stairs, followed by the opening of the door at No. 17, it could be he, I accept that."
Winter nodded again. Apparently he was content with Theydon's correction.
