The Master Detective: Being Some Further Investigations of Christopher Quarles

by Percy James Brebner

Exactly at what point my investigations had jeopardized his secret I could not find out, but he evidently thought it was in danger, and believing Quarles was responsible, he determined to get rid of him.

I was told that he had made two attempts upon his life before the night he was introduced to him in the Temple. That night Quarles was followed when he left the Temple, and, as we know, was shot at in Savoy Street.

This attempt failing, the doctor, who had already asked Quarles to dinner on the following night as an extra precaution, determined to use a method which had already proved successful.

Quarles's enthusiasm for psychological research could hardly fail to tempt him into the trap.

No. 7 Manleigh Road belonged to a man in the doctor's employment. It had been prepared for eventualities some time before—probably tragedies had occurred in the house which had never been heard of. The house agent was one of the gang, and when, either by mistake or because he could not help himself without causing undesirable comment, he let the house to the young married couple, they were frightened away. The house was then let to Greaves, a man who had become a danger to the doctor, and in due course he was found dead in his bed.

Between the fireplace of the haunted room and that of the corresponding room in No. 5 part of the chimney wall had been removed, so that there was sufficient space for the ape to get from one room to the other.

This ape, some four feet in height, was exceedingly powerful and more than usually imitative, but was not naturally vicious. Any action done in its presence the animal would be certain to repeat at the first opportunity; but having done so, it did not repeat it again unless the action was performed again. The action of strangling a man in his sleep by means of a cord was performed before the ape, and afterwards the animal was allowed to steal through the hole in the chimney. The result was that Greaves was found dead.

It was intended that Quarles should die in a like manner, and special pains were taken with the ape to insure success. The action was performed before the animal in every detail more than once, and it was kept in strict confinement until the right moment came.

The ape was out of my sight, but I chanced to see the imitation in progress on the Thursday night through the glass, which had unaccountably been left open for some minutes after it had been tried to see that it was in working order. I saw only dimly because the imitation was being done by the light of a single candle, and that shaded as much as possible, to suggest to the ape the gloomy conditions of the room in which it was to repeat its lesson. Let into the wall of the room in the boarding-house there was a glass backing on to the one in the haunted room. A small handle swung aside the back, which was common to both, and the looking-glass became a window from one room to the other.

When he fired Quarles evidently hit the ape. Mad with pain, the animal dashed back through the hole in the chimney and attacked the doctor, who was probably taken entirely unawares, as he was looking through the glass to see what the revolver shot might mean.
