ten o'clock before
I must follow this man -- it 's the Foggatt case . '' As he went out I heard a cab rattle away , and immediately after it another . I paid the bill and went home . It was ten o'clock before Hewitt turned up , calling in at his office below on his way up to me . `` Mr. Sidney Mason , '' he said , `` is the gentleman the police will be wanting to-morrow , I expect , for the Foggatt murder . He is as smart a man as I remember ever meeting , and has done me rather neatly twice this evening . '' `` You mean the man we sat opposite at Luzatti 's , of course ? ''
