Kneeling, Lanyard drew from beneath the berth his bellows-bag, selected
from its contents a black japanned tin case containing a rather elaborate
though compact trench medicine kit, the idle purchase of an empty afternoon
in London. Extracting from its fittings a small leather-covered case, he
replaced the kit, relocked and shoved the bag back beneath the berth.

Then, standing over the hand-basin, he opened the leather-covered case. Its
velvet-lined compartments held a hypodermic syringe and needle, and a glass
phial of twenty-four one-thirtieth grain morphia tablets.

Uncorking the phial, he shook out all the tablets, replaced three, then
slid the paper cylinder into the tube; it fitted precisely, concealed by
the label of the manufacturing chemist, leaving room for six more tablets.
Lanyard inserted four on top of the cylinder, moistening the lowermost
slightly to make it stick, recorked the phial, and returned it to its
compartment.

Next he dissolved three morphia tablets in a little water in the bottom of
a glass, filled the syringe with the strong solution, fitted on the needle,
squirted most of the contents down the waste-pipe, and consigned the
remaining tablets to the same innocuous fate.

Finally he replaced needle and syringe in the case, let the glass which had
held the solution stand without rinsing, and put the open case upon the
shelf above the basin.

A light tapping sounded on the panels of his door.

"Well? Who's there?"
