Stobb, a big, cheery-faced man, who looked like a highly respectable publican, turned to Brereton with a smile. "It was a very easy job, sir," he said. "I found out all about the lady and her connexion with Woking in a very few hours. There are plenty of folk at Woking who remember Miss Pett--she gave you the mere facts of her residence there correctly enough. But--naturally--she didn't tell you more than the mere facts, the surface, as it were. Now, I got at everything. Miss Pett was housekeeper at Woking to a Major Stilman, a retired officer of an infantry regiment. All the time she was with him--some considerable period--he was more or less of an invalid, and he was well known to suffer terribly from some form of neuralgia. He got drugs to alleviate the pain of that neuralgia from every chemist in the place, one time or another. And one day, Major Stilman was found dead in bed, with some of these drugs by his bedside. Of course an inquest was held, and, equally of course, the evidence of doctors and chemists being what it was, a verdict of death from misadventure--overdose of the stuff, you know--was returned. Against Miss Pett there appears to have been no suspicion in Woking at that time--and for the matter of that," concluded Mr. Stobb drily, "I don't know that there is now." "You have some yourself?" suggested Brereton. "I went into things further," answered Mr. Stobb, with the ghost of a wink. "I found out how things were left--by Stilman. Stilman had nothing but his pension, and a capital sum of about two thousand pounds. He left that two thousand, and the furniture of his house, to Miss Pett. The will had been executed about a twelvemonth before Stilman died. It was proved as quickly as could be after his death, and of course Miss Pett got her legacy. She sold the furniture--and left the neighbourhood." "What is your theory?" asked Brereton. Mr. Stobb nodded across the table at Carfax. "Not my business to say what my theories are, Mr. Brereton," he answered. "All I had to do was to find out facts, and report them to Mr. Carfax and Mr. Wraythwaite." "All the same," said Brereton quietly, "you think it quite possible that Miss Pett, knowing that Stilman took these strong doses, and having a pecuniary motive, gave him a still stronger one? Come, now!" Stobb smiled, rubbed his chin and looked at Carfax. And Carfax pointed to Stobb's partner, a very quiet, observant man who had listened with a sly expression on his face. "Your turn, Leykin," he said. "Tell the result of your inquiries." Leykin was one of those men who possess soft voices and slow speech. Invited to play his part, he looked at Brereton as if he were half apologizing for anything he had to say.
