The Spider by Fergus Hume — Read

It was quite three days before Colonel Towton was enabled to have an interview with Vernon. He certainly wrote to him at once, but on receiving no reply he telephoned, only to learn that his friend had been unexpectedly called from town on the same evening. Towton therefore had to possess his soul in patience, and remained in his rooms recovering from the assault. And this took some little time.

The attempt at strangulation by the burly Hindoo -- who was a different person to the slim doorkeeper -- had caused the Colonel's neck to swell, as the flesh was bruised and chafed. His windpipe also felt painful owing to the strong compression, and for twenty-four hours he had found it difficult to swallow with ease. Towton recognised only too uneasily that he had been within a short distance of actual death, and perhaps would have been strangled outright had not Diabella, as he verily believed, stopped her too zealous servant. Naturally, she did not wish for a client's death lest the police should interfere and put an end to her lucrative trade, which was assuredly a very paying one.
