mouth, and quitted his tenement of clay, leaving those glassy eyes set
hideously upon us.

"The pagan gods fight upon our side," said Smith strangely. "Elms have a
dangerous habit of shedding boughs in still weather--particularly after
a storm. Pan, god of the woods, with this one has performed Justice's
work of retribution."

"I don't understand. Where was this man--"

"Up the tree, lying along the bough which fell, Petrie! That is why he
left no footmarks. Last night no doubt he made his escape by swinging
from bough to bough, ape fashion, and descending to the ground somewhere
at the other side of the coppice."

He glanced at me.

"You are wondering, perhaps," he suggested, "what caused the mysterious
light? I could have told you this morning, but I fear I was in a bad
temper, Petrie. It's very simple: a length of tape soaked in spirit or
something of the kind, and sheltered from the view of any one watching
from your windows, behind the trunk of the tree; then, the end ignited,
lowered, still behind the tree, to the ground. The operator swinging it
around, the flame ascended, of course. I found the unburned fragment of
the tape last night, a few yards from here."

I was peering down at Fu-Manchu's servant, the hideous yellow man who
lay dead in a bower of elm leaves.

"He has some kind of leather bag beside him," I began--

"Exactly!" rapped Smith. "In that he carried his dangerous instrument of
death; from that he released it!"

"Released what?"

"What your fascinating friend came to recapture this morning."

"Don't taunt me, Smith!" I said bitterly. "Is it some species of bird?"

"You saw the marks on Forsyth's body, and I told you of those which I
had traced upon the ground here. They were caused by claws, Petrie!"

"Claws! I thought so! But what claws?"

"The claws of a poisonous thing. I recaptured the one used last night,
killed it--against my will--and buried it on the mound. I was afraid to
throw it in the pond, lest some juvenile fisherman should pull it out
and sustain a scratch. I don't know how long the claws would remain
venomous."

"You are treating me like a child, Smith," I said slowly. "No doubt I
am hopelessly obtuse, but perhaps you will tell me what this Chinaman
carried in a leather bag and released upon Forsyth. It was something
which you recaptured, apparently with the aid of a plate of cold turbot
and a jug of milk! It was something, also, which Karamaneh had been sent
to
