"From the first Howells was satisfied with me," Bobby said.
Graham flung up his hands.
"Then tell me how you got in without disturbing those locks. I grant you, Bobby, you had sufficient motive for both murders, but I don't believe you have two personalities, one decent and lovable, the other cruel and cunning to the point of magic. I don't believe if a man had two such personalities the actions of one would be totally closed to the memory of the other."
Bobby smiled wanly.
"It isn't pleasant to confess it, Hartley, but I have read of such cases."
"Fiction!"
"Scientific fact."
"I wish to the devil I had shared your room with you to-night," Graham muttered. "I might have furnished you an alibi for this affair at least."
"Either that," Bobby answered frankly, "or you might have followed me and learned the whole secret. Honestly, isn't that what you were thinking of, Hartley? And I did go to sleep, telling myself it would help me if something of the sort happened to Howells. Now I'm not so sure that it will. I—I suppose you've got to notify the police."
Graham held up his hand.
