There was nobody in save the one manservant he kept by the day, and he passed into the dining-room overlooking the street. He had work to do and it had to be done quickly. In one of the walls was set a stout safe, and this he opened, taking from it a steel box which he carried to the table. There was a fire laid on the hearth and to this he put a match though the day was warm enough. Then he proceeded to unlock the box. Apparently it was empty, but, taking out his scarf-pin, he inserted the point in a tiny hole, which would have escaped casual observation, and pressed. Half the steel bottom of the box leapt up, disclosing a shallow cavity beneath. The colonel stared. There had been two letters put in there, letters which he had put away against the moment when it might be necessary to bring a recalcitrant agent to heel. They had gone. He slid his fingers beneath the half of the bottom which had not opened and felt a card. He drew this out and looked at it, licking his lips the while. For the space of a minute he stared and stared at the Knave of Clubs he held in his hand. A Knave of Clubs signed with a flourish across its face: "Jack o' Judgment." Then he flung the card into the fire and, walking to the sideboard, splashed whisky into a tumbler with a hand that shook. CHAPTER XII BUYING A NURSING HOME The building in which Colonel Boundary had his beautiful home was of a type not uncommonly met with in the West End of London. The street floor was taken up entirely with shops, the first floor with offices and the remainder of the building was practically given over to the colonel. One by one he had ousted every tenant from the building, and practically the whole of the fourteen sets of apartments which constituted the residential portion of the building was held by him in one name or another. Some he had obtained by the payment of heavy premiums, some he had secured when the lease of the former tenant had lapsed, some he had gathered in by sub-hiring. He had tried to buy the building, since it served his purpose well, but came against a deed of trust and the Court of Chancery, and had wisely refrained from going any further into a matter which must bring him vis-à-vis with a Master in Chancery, with all the publicity which such a transaction entailed. Nor had he been successful in acquiring any of the premises on the first floor. They were held by three very old established businesses--an estate agent, a firm of land surveyors and the offices of a valuer. He missed his opportunity, at any rate, of securing the business of Lee and Hol, the surveyors, and did not know it was in the market until after it had been transferred to a new owner. But they were quiet, sober tenants, who closed their offices between five and six every night and did not open them until between nine or ten on the following morning, and their very respectability gave him a certain privacy.
