Meanwhile Bindle deliberated. If he retained the keys there would be suspicion at the flats, and perhaps locks would be changed; if, on the other hand, the keys were returned immediately, the owner would trouble himself no further.

At this juncture he was not very clear as to what he intended to do. He was still undecided when the four keys were handed to him in return for a shilling.

The mind of Joseph Bindle invariably responded best to the ministrations of beer, and when, half an hour later, he left the bar of the Purple Goat, his plans were formed, and his mind made up. He vaguely saw the hand of Providence in this discovery of Professor Conti's keys, and he was determined that Providence should not be disappointed in him, Joseph Bindle.

First he bought a cheap electric torch, guaranteed for twelve or twenty-four hours—the shopkeeper was not quite certain which. Then, proceeding to a chemist's shop, he purchased a roll of medical bandaging. With this he retired up a side street and proceeded to swathe his head and the greater part of his face, leaving only his eyes, nose, and mouth visible. Drawing his cap carefully over the bandages, he returned to the highway, first having improvised the remainder of the bandaging into an informal sling for his left arm. Not even Mrs. Bindle herself would have recognised him, so complete was the disguise.

Ten minutes later he was at Audrey Mansions. No one was visible, and with great swiftness and dexterity he tried the duplicate keys in the open outer door. One fitted perfectly. Mounting to the third floor, he inserted the other in the door of No. 13. The lock turned easily. Quite satisfied, he replaced them in his pocket and rang the bell. There was no answer. He rang again, and a third time, but without result.

"Does 'is own charin'," murmured Bindle laconically, and descended to the ground floor, where he rang the porter's bell, with the result that the keys were faithfully redeemed.

Bindle left the porter in a state of suppressed excitement over a vivid and circumstantial account of a terrible collision that had just taken place in the neighbourhood, between a motor-bus and a fire-engine, resulting in eleven deaths, including three firemen, whilst thirty people had been seriously injured, including six firemen. He himself had been on the front seat of the motor-bus and had escaped with a broken head and a badly-cut hand.

Professor Conti did not discover his loss until the porter handed him his keys, enquiring at the same time if the Professor had heard anything of the terrible collision between the motor-bus and fire-engine. The Professor had not. He mounted to his flat with heavy steps. He was tired and dispirited. In his bedroom he surveyed himself mournfully in the mirror as he undid the buckle of his ready-made evening-tie, which he placed carefully in the green cardboard box upon the dressing-table. In these days a tie had to last the week, aided by the application of French chalk to the salient folds and corners.

Professor Sylvanus Conti, who had been known to his mother, Mrs. Wilkins, as Willie, emphasised in feature and speech his cockney origin. He was of medium height, with a sallow complexion—not the sallowness of the sun-baked plains of Italy, but rather that of Bermondsey or Bow.
