"God knows, Petrie; but I fear--"

Behind us, along the highroad, a tramcar went rocking by, doubtless
bearing a few belated workers homeward. The stark incongruity of the
thing was appalling. How little those weary toilers, hemmed about with
the commonplace, suspected that almost within sight from the car
windows, in a place of prosy benches, iron railings, and unromantic,
flickering lamps, two fellow men moved upon the border of a
horror-land!

Beneath the trees a shadow carpet lay, its edges tropically sharp; and
fully ten yards from the first of the group, we two, hatless both, and
sharing a common dread, paused for a moment and listened.

The car had stopped at the further extremity of the common, and now
with a moan that grew to a shriek was rolling on its way again. We
stood and listened until silence reclaimed the night. Not a footstep
could be heard. Then slowly we walked on. At the edge of the little
coppice we stopped again abruptly.

Smith turned and thrust his pistol into my hand. A white ray of light
pierced the shadows; my companion carried an electric torch. But no
trace of Eltham was discoverable.

There had been a heavy shower of rain during the evening just before
sunset, and although the open paths were dry again, under the trees
the ground was still moist. Ten yards within the coppice we came upon
tracks--the tracks of one running, as the deep imprints of the toes
indicated.
