"--from which he returned to his house in Marchmont Avenue at about 1 a.m. He went upstairs immediately and was undressing when he heard a suspicious sound in his study. A moment later a shot rang out. Stopping only to pull on a dressing-gown, Mr. Raegenssen hastened downstairs and found the window wide open and his safe broken open. Finding that the telephone wires had been cut, Mr. Raegenssen returned to his bedroom in order to don some clothes before summoning the police." "Decency before duty," Storm drawled. "Two constables who had heard the shot, however, had already arrived, and had entered the building by way of the window which the burglar had left open in his flight. Mr. Raegenssen, meanwhile, had heard a noise in the room adjoining his bedroom which led him to suspect that the burglar was perhaps still in the house. This, indeed, proved to be the case, and the two officers, assisted by Mr. Raegenssen, attempted to apprehend the man. The burglar, however, who was masked and evidently a dangerous character, drew a pistol and fired several times at his would-be captors without hitting them, after which he made a desperate and successful bid for safety. "About two and a half hours later, when Mr. Raegenssen who had been too disturbed by the thrilling incident to return immediately to his bed, was working in his library, he heard a suspicious sound in his study and attempted to investigate it. He was promptly attacked with great ferocity by the desperado, who again contrived to make his escape, but who this time left behind him a silver triangle of a type which is by now familiar to readers of the _Evening Record_.

Fifteen love. "--made to abstract anything of value. The only things interfered with were the safe and a number of drawers and filing cabinets in which Mr. Raegenssen kept private papers concerning his business. "Inspector Teal, who is working on the Triangle Mystery in conjunction with Captain Arden, has been called in, and he is said to have made an important discovery, which is at present being kept a strict secret." "How much did you lend this reporter, Teal?" asked Storm accusingly. "It will be remembered that Mr. Raegenssen had already been the recipient of one of the warnings of the Alpha Triangle. "Good old Snooper!" said Storm cryptically. "I knew he'd get away with it somehow!" He pitched the paper into a corner and swung himself off the table. "And an inquiry. Well, I'll deal with the inquiry! But I wish I knew who Oscar's second friend was." "It wasn't you?" Inspector Teal was incredulous.
