"I knew there was a risk, but we were helpless," Quarles answered. "I had heard of No. 6 and its inhabitants soon after one o'clock, but if we had gone to the house in daylight we should only have hurried a tragedy probably. Besides, I had a theory. These villainous societies almost invariably have methods and rules. If a member is dispatched, some semblance of justice is given to his sentence. I thought the men who had done the kidnapping were not of the first importance, and that Mrs. Fitzroy would not be done away with before she had been confronted with some chief member of the gang. It was very necessary they should wring a confession from her if they could."

Early next morning two houses in Soho were raided and a number of arrests made; but, except for the two men we had taken in Hambledon Road, I do not think we got hold of anybody of importance. The raid, at any rate, did something to disturb a nest of anarchists, and, with the information in the hands of the Continental police through Jacob Morrison, and with what Mrs. Fitzroy could tell us, the society was scattered, and their efforts are likely to be moribund for some time. Mrs. Fitzroy was an Englishwoman married to an Italian, who had been a member of the society and had been done to death by his associates some four years ago. She said he was innocent and was determined to avenge him. The man who had killed Morrison had been shot by Quarles. He was the cigarette smoker. His two companions whom we had captured got terms of imprisonment, and will be deported on their release. I can only trust that Mrs. Fitzroy will keep out of their way then.

CHAPTER VI
THE MYSTERY OF "OLD MRS JARDINE"

My association with Professor Quarles undoubtedly had an effect upon my method of going to work in the elucidation of mysteries, and not always with a good result. His methods were his own, eminently successful when he used them, but dangerous in the hands of others. In attempting to theorize I am convinced I have sometimes lost sight of facts.

I am not sure that this reflection applies to the case of old Mrs. Jardine, but somehow my mind never seemed to get a firm grip of the affair. I was conscious of being indefinite, and had an unpleasant sensation that I had failed to see the obvious.

Old Mrs. Jardine lived at Wimbledon, in a house of some size standing in a well-grown garden. She was an invalid, confined to the house—indeed, to three or four rooms which opened into one another on the first floor—and she must have been an absolute annuity to Dr. Hawes, who visited her nearly every day. The household consisted of old Mrs. Jardine, Mrs. Harrison, also an elderly lady, who was her companion, Martha Wakeling, housekeeper and cook, who had been many years in her service; and a housemaid named Sarah Paget.

Into this household, in which no one took any particular interest, came tragedy, and the Wimbledon mystery developed into a sensation.

Early one morning Sarah Paget arrived at the doctor's, saying her mistress had been taken suddenly ill, and would he come immediately. She did not know what was the matter. The cook had sent her.

Three days before Dr. Hawes had gone away for a holiday, and his practice was in the hands of a locum, a young doctor named Dolman. He went at once. Mrs. Jardine was dead upon her bed. She had been found in the morning by Martha Wakeling lying just as the doctor saw her. She had been attacked in her sleep, Dolman thought, and her head had been smashed with some heavy instrument; Mrs. Harrison, the companion, had disappeared. Of course, the police were sent for at once, and the case came into my hands that same day.
