"Do you know of any woman who was likely to visit him at that time of night?"
"Great heavens, no, man! Do you suspect a woman? He——" He checked himself, and looked curiously at the detective. "Mr. Grell was a friend of mine," he went on more quietly. "Things are bad enough as they are, but you know that he had influential friends both here and in America. They won't thank you, Mr. Foyle, for trying to go into such things."
Heldon Foyle's eyes lingered in quiet scrutiny on the other's face.
"I shall do what I consider to be my duty," he said, his voice a little hard. "Come, Sir Ralph, you will see I must do my best to bring the murderer of this man to justice. Had Mr. Grell any relations?"
"I don't believe there's one in the wide world."
"And you don't remember what time he left? Try, Sir Ralph. It is important. Before you came I sent a man to the club, and none of the servants recollects seeing either of you go. They say he was with you most of the evening. You can clear up this matter of time."
"I don't remember what time he left me."
The baronet's voice was hoarse and strained. Foyle rose and stood towering over him.
"You are lying," he said deliberately.
