regard for the figure; he considered himself as fit at forty as any man in England, and he gave chase[Pg 24] with his usual confidence. But the long-legged doctor would have left him behind with the lamp-posts, but for the fact that he was really tearing toward the sound, not flying from it as his pursuer was so ready to suppose. In a matter of seconds they had both fetched up at a brilliantly lighted house, where a more than usually obese policeman was alternately pounding on the door and splitting the sober welkin with his whistle. [Pg 24] "Stop that infernal row!" cried Doctor Dollar, with incensed authority. "Out of the way with you—this is my house!" And the Home Secretary arrived on the scene of an imminent assault on his police, just in time to divert the outraged officer's attention by asking what had happened, while the doctor found his key. "Lord only knows!" said the policeman, kicking some broken glass on one side. "Murder, it sounds like; there's somebody been loosing off——" And even as he spoke somebody loosed off again! The terrific report was followed by screams within and a fresh shower of glass from the fanlight. But by this time Doctor Dollar had his latch-key in the[Pg 25] lock.

[Pg 25] Dollar exclaimed "Barton!" in blank amazement. But it was not the unlucky Barton who had run amuck. "They won't let me at him! They'll get the lot of us shot dead!" he spluttered, with ungrateful objurgations; and then the newcomers grasped the situation. On the stairs, at the end of the narrow passage, they beheld an enormous revolver, against a background of pink sleeping-suit, with a ferocious eye looking down the barrel. The crime doctor slipped in front of the Hogarthian group, and stood between everybody and the armed man—shaking his head with an expression that nobody else could see. "Ozzie, I'm surprised at you!" they heard him say with severity. "I thought you were a better sportsman than to go playing the fool the one night I'm out. If you want to frighten people, do it where you don't damage their property; if you mean[Pg 26] murder, I'm your mark, my lad! Aim at my waistcoat buttons
