He sought an interview with the chief commissioner, and that same night, accompanied by a small army of detectives, he made a systematic search of Silvers Rents. The house into which Jasper Cole had been seen to enter was again raided, and again without result. The house was empty save for one room, a big room which was simply furnished with a truckle-bed, a table, a chair, a lamp, and a strip of carpet. There were four rooms—two upstairs, which were never used, and two on the ground floor.
At the end of a passage was a kitchen, which also was empty, save for a length of bamboo ladder. From the kitchen a bolted door led on to a tiny square of yard which was separated by three walls from yards of similar dimensions to left and right and to the back of the premises. At the back of Silvers Rents was Royston Court, which was another cul-de-sac, running parallel with Silvers Rents.
Mr. Mann returned to the house, and again searched the upstairs rooms, looking particularly for a trapdoor, for the bamboo ladder suggested some such exit. This time, however, he completely failed. Jasper Cole, he found, had made only one visit to the house since John Minute's death.
It is a curious fact, as showing the localizing of interest, that Silvers Rents knew nothing of what had occurred almost at its doors, and, though it had at its finger tips all the gossip of the docks and the Thames Iron Works, it was profoundly ignorant of what was common property in Royston Court. It is even more remarkable that Saul Arthur Mann, with his squadron of detectives, should have confined their investigations to Silvers Rents.
The investigator was baffled and disappointed, but by the oddest of chances he was to pick up yet another thread of the Minute mystery, a thread which, however, was to lead him into an ever-deeper maze than that which he had already and so unsuccessfully attempted to penetrate.
Three days after his search of Silvers Rents, business took Mr. Mann to Camden Town. To be exact, he had gone at the request of the police to Holloway Jail to see a prisoner who had turned state's evidence on a matter in which the police and Mr. Mann were equally interested. Very foolishly he had dismissed his taxi, and when he emerged from the doors there was no conveyance in sight. He decided, rather than take the trams which would have carried him to King's Cross, to walk, and, since he hated main roads, he had taken a short cut, which, as he knew, would lead him into the Hampstead Road.
Thus he found himself in Flowerton Road, a thoroughfare of respectable detached houses occupied by the superior industrial type. He was striding along, swinging his umbrella and humming, as was his wont, an unmusical rendering of a popular tune, when his attention was attracted to a sight which took his breath away and brought him to a halt.
It was half past five, and dull, but his eyesight was excellent, and it was impossible for him to make a mistake. The houses of Flowerton Road stand back and are separated from the sidewalk by diminutive gardens. The front doors are approached by six or seven steps, and it was on the top of one of these flights in front of an open door that the scene was enacted which brought Mr. Mann to a standstill.
The characters were a young man and a girl. The girl was extremely pretty and very pale. The man was the exact double of Frank Merrill. He was dressed in a rough tweed suit, and wore a soft felt hat with a fairly wide brim. But it was not the appearance of this remarkable apparition which startled the investigator. It was the attitude of the two people. The girl was evidently pleading with her companion. Saul Arthur Mann was too far away to hear what she said, but he saw the young man shake himself loose from the girl. She again grasped his arm and raised her face imploringly.
Mr. Mann gasped, for he saw the young man's hand come up and strike her back into the house. Then he caught hold of the door and banged it savagely, walked down the stairs, and, turning, hurried away.
