Leaving the doctor in this gallant position for a few seconds, we step aside to inform the reader of a circumstance or two with which it is right he should be made acquainted. In the first place, he should be, as he now is, informed that the person at the door, and whom the doctor took to be a midnight robber, was no other than the doctor's neighbour, Mr. Thomson himself, the lawful occupant of the house of which the former had taken possession. He had happened, like the doctor, to have been out late that night; and, like the doctor, too, was several sheets in the wind. However, that is neither here nor there to our story. But it is of some consequence to it to add, inasmuch as it accounts for the non-appearance of any one to avert the impending catastrophe, that there was no one residing in Mr. Thomson's house at the particular period of which we speak, but Mr. Thomson himself; his wife, children, and servant, being at sea-bathing quarters. Thus, then, it was that the doctor had been allowed to take and keep such undisturbed possession of the premises. Again, the doctor being a bachelor, kept no servant at all; the domestic duties of his establishment being performed by an old woman, who came at an early hour of the morning, remained all day, and left at night. There was thus no family circumstance connected with his own domestic establishment, the absence of which, on the present occasion, might have excited his suspicions as to his real position. Everything, then, favoured the unlucky chance now in progress. To resume: The doctor having placed himself in the hostile attitude already described, coolly and courageously awaited the entrance of the supposed burglar. He had not to wait long. The door opened; and, all unconscious of what was awaiting him, Thomson entered. It was all he was allowed to do, however; for, in the next instant, a well-directed blow from the doctor's crab-stick laid him senseless on the floor. "Take that, you burglarious villain," shouted the doctor triumphantly, on seeing the success of his assault; "and that, and that, and that," he added, plunging sundry forcible kicks into the body of his prostrate victim with the points of his little stumpy Hessians. Having settled his man, as he imagined, the doctor stooped down, and, seizing him by the neck of his coat, proceeded to drag him to the outside of the door. This was a work of some difficulty, as Thomson was rather a heavy man; but it was accomplished. The doctor exerted himself, and succeeded in hauling the unconscious body of his unfortunate neighbour on to the landing-place on the outside. Having got him there, he edged him towards the descent, and, giving him a shove with his foot, sent him rolling down the stairs.
