"Not he," said Mr. Bruff. "He would never have dismissed his two policemen, if he had run the risk of keeping the Diamond in his own house again." We waited another half-hour for the boy, and waited in vain. It was then time for Mr. Bruff to go to Hampstead, and for me to return to Rachel in Portland Place. I left my card, in charge of the porter at the chambers, with a line written on it to say that I should be at my lodgings at half past ten, that night. The card was to be given to the boy, if the boy came back. Some men have a knack of keeping appointments; and other men have a knack of missing them. I am one of the other men. Add to this, that I passed the evening at Portland Place, on the same seat with Rachel, in a room forty feet long, with Mrs. Merridew at the further end of it.
