The visitor looked very much relieved. "I'm perfectly sure of it," he cried. "My friend had nothing to do with this case." "I'm glad to hear it. Who is he?" "The man who has been arrested in this restaurant murder case." "John Jones?" "That is the name he has given to the police." "But isn't that his right name?" "I--I don't know," stammered the visitor. "He must be a very particular friend of yours, since you don't know what his name is!" "I never saw him in my life." "Look here, Mr.--" "Hammond is my name." "Well, Mr. Hammond, your statements don't hang together. You began by saying that this man was your friend." "I didn't mean that exactly, but I sympathize with him. It must be terrible to be arrested for such a crime and to find the evidence growing stronger in spite of your innocence." "How do you know that he is innocent?" Before Hammond could reply there came a knock at the door. Nick answered it. "Come in, Gaspard," he said, throwing the door wide open. "You sent for me, and--Good God! who is this?" "You know him, then?" "Yes, yes, I know him," cried Gaspard; "he is the man who was in room A last night." CHAPTER V. PATSY'S TIP. Gaspard's declaration produced a stunning effect upon Hammond. At first he seemed thunderstruck. There was a look in his face which made Nick say to himself, "It isn't true." But whether the accusation was true or false, Nick knew at once that Hammond recognized Gaspard. Yet he couldn't be a regular visitor to the place, because Gaspard had said that he had never seen either of the two men before the fatal evening. Therefore, as Hammond had recognized Gaspard, he must be the man who was in room A, because the man in room B had not seen the head waiter, according to Gaspard's story. Hammond, after the first shock of surprise, recovered his nerve wonderfully. He calmly took a chair and sat there in deep thought for nearly five minutes. He paid no attention to questions. Finally he looked up and said: "I don't know why I should deny it to you. There is no charge against the man in room A." "None whatever," said Nick. "He is wanted merely as a witness." "It occurred to me that you might have some theory of a conspiracy in which both men were concerned." "I never thought of it." "Then I am not to be put under arrest?" "Certainly not, unless some new evidence appears, and I do not expect it." "Very well; I was the man in room A." "And who was the lady?" "I decline to mention her name. She has nothing to do with this case. You will easily understand that I do not wish to bring a lady's name into a tragedy of this kind." "I can understand that. Now tell me why you feel so sure of this man Jones' innocence." "Will you promise to keep me out of this affair as much as you can?" "Why do you wish it? What are you afraid of?"
