rcus should be summoned to this prepared telephone; for it
formed no part of the plan for myself to appear anywhere in the
neighborhood at the time of the experiment. I was of course compelled
to pay a secret visit to the Red House for the purpose of installing
the telephone device, and at the same time I installed the bell. This
was worked from a small storage battery and I arranged that by the
opening of the garage door the bell would be put in motion and by the
closing of the door at the end of the same building the ringing would
cease.

A simple contrivance screwed to both doors made this possible, but I
know not by whose hand the ringing would have been accomplished if it
had not been for one of those brilliant suggestions of Nahemah's,
which hovered between the domain of genius and that of fiendishness.

She proposed that she should ring up the local police depot and ask
the constable on that beat to lock the garage, thus making him the
direct instrument for the removal of Sir Marcus!

I knew, since I myself had been a resident in this district, that a
constable patrolled College Road at an hour roughly corresponding with
that at which it was proposed to cause Sir Marcus to visit the Red
House; and because all strategy is based upon the clock, a brief
survey of the facts convinced me that Nahemah's plan was feasible.

Thus, it was Police-Constable Bolton, whose evidence has appeared in
the press, who actually killed Sir Marcus Coverly! I come now to the
dangerous attitude adopted by Nahemah immediately after the event.

We had had a case of suitable dimensions made for containing the body,
and had had it delivered at the Red House garage, where it was
received by a district messenger instructed for the purpose. Upon me
devolved the task of carrying the body from the supper-room to the
garage--a task which I performed shortly after the departure of
Police-Constable Bolton. I packed the body, removed the telephone and
also all traces of the bell-device.

The same carter had instructions to call for the case in the morning,
and the garage door was left open to enable him to collect it. In
short, except for these two essential visits, one before and one after
the experiment, there was no occasion for myself or Nahemah to appear
in the neighborhood of the Red House.

But that cat-like spirit of impish mischief which possessed her at
this season (and especially at night) together with an almost insane
joy which
