"We now come to the second alternative--was the deceased the victim of homicide? In order to answer that question in the affirmative it is essential that we should be able to form some conception of the _modus operandi_. It is all very well for Dr. Robinson to say the cut was made by another hand; but in the absence of any theory as to how the cut could possibly have been made by that other hand, we should be driven back to the theory of self-infliction, however improbable it may seem to medical gentlemen. Now, what are the facts? When Mrs. Drabdump and Mr. Grodman found the body it was yet warm, and Mr. Grodman, a witness fortunately qualified by special experience, states that death had been quite recent. This tallies closely enough with the view of Dr. Robinson, who, examining the body about an hour later, put the time of death at two or three hours before, say seven o'clock. Mrs. Drabdump had attempted to wake the deceased at a quarter to seven, which would put back the act to a little earlier. As I understand from Dr. Robinson, that it is impossible to fix the time very precisely, death may have very well taken place several hours before Mrs. Drabdump's first attempt to wake deceased. Of course, it may have taken place between the first and second calls, as he may merely have been sound asleep at first; it may also not impossibly have taken place considerably earlier than the first call, for all the physical data seem to prove. Nevertheless, on the whole, I think we shall be least likely to err if we assume the time of death to be half-past six. Gentlemen, let us picture to ourselves No. 11 Glover Street at half-past six. We have seen the house; we know exactly how it is constructed. On the ground floor a front room tenanted by Mr. Mortlake, with two windows giving on the street, both securely bolted; a back room occupied by the landlady; and a kitchen. Mrs. Drabdump did not leave her bedroom till half-past six, so that we may be sure all the various doors and windows have not yet been unfastened; while the season of the year is a guarantee that nothing had been left open. The front door through which Mr. Mortlake has gone out before half-past four, is guarded by the latch-key lock and the big lock. On the upper floor are two rooms--a front room used by deceased for a bedroom, and a back room which he used as a sitting-room. The back room has been left open, with the key inside, but the window is fastened. The door of the front room is not only locked, but bolted. We have seen the splintered mortise and the staple of the upper bolt violently forced from the woodwork and resting on the pin. The windows are bolted, the fasteners being firmly fixed in the catches. The chimney is too narrow to admit of the passage of even a child. This room, in fact, is as firmly barred in as if besieged. It has no communication with any other part of the house. It is as absolutely self-centered and isolated as if
