"People who take their own lives sometimes have curious hallucinations. I have known many. Suicide is a fascinating, if very grim study." "Then you really think this is a case of suicide?" "I can, I fear, give no opinion until after the post-mortem, Mr Sainsbury," was Sir Houston's guarded reply, his face grave and thoughtful. "But it is all so strange, so remarkable," exclaimed the younger man. "Why did he tell me that he'd been shot, if he hadn't?"
