The kitchen door, which he had taken especial pains to assure himself was locked, when he had made the rounds immediately after the departure of Captain Strawn and his men, was standing slightly ajar!
Someone had entered this house!
Dundee stared blankly at the door, which was equipped with a Yale lock. Someone with a key.... But why had the door been left ajar? To make escape more noiseless?
With the toe of his shoe Dundee pushed the door to and heard the click of the lock, then, all thought of food routed from his mind, made a quick but almost silent dash into the dining room to secure one of the pair of tall wax tapers, which, in their silver candlesticks, served as ornaments for the sideboard.
If the intruder was still in the house he could be nowhere but in that unfinished half of the gabled top story. The nearer stairs were those in the back hall, and Dundee took them two at a time, regardless of the noise. Who had preceded him stealthily?... By the aid of his lighted candle he discovered an electric switch at the head of the stairs, flicked it on, and found himself in a wide hall, one wall of which was finished with buff-tinted plaster and with three doors, the other of rough boards with but a single door.
With his candle held high, so that its light should not blind him, and well aware that it made him a perfect target, Dundee opened the unpainted door and found himself in the dark, musty-smelling room that had served Nita Selim and the Crains before her as a storeroom. From the ceiling dangled a green cord ending in a cheap, clear-glass bulb, but its light was sufficient to penetrate even the farthest low nooks made by the three gables. He blew out his candle and dropped it, as useless now.
A quick tour convinced him that nothing human was concealed behind one of Nita Selim's empty wardrobe trunks, or behind one of the several pieces of heavy old furniture, undoubtedly left behind by the dispossessed Crain family.
Big footprints on the thick dust which coated the floor showed him that he was being no more thorough than Captain Strawn's brace of plainclothes detectives had been much earlier that evening. Two pairs of giant footprints....
With an exclamation he discovered a smaller, narrow pair of prints, and followed their winding trail all around and across the attic. And then he remembered.... Ralph Hammond's footprints, of course, made that morning as he went about his legitimate business of measuring and estimating for the job of turning the storeroom into bedrooms and bathrooms.
Dundee had not realized that he was frightened until he was in the hall again, facing one of the three doors in the plastered wall. With surprise, and some amusement, he became aware that his hands were trembling, and that his knees had a curious tendency to buckle.
