loud and steady. The world outside seen through the open
end of the shed seemed incredibly dim and remote. It seemed absolutely
silent, too, since the riot of the machinery drowned every external
sound. Far away was the black fence of the yard with grey shadowy
houses behind, and above was the deep blue sky and the pale little
stars. Azuma-zi suddenly walked across the centre of the shed above
which the leather bands were running, and went into the shadow by
the big dynamo. Holroyd heard a click, and the spin of the armature
changed.

"What are you dewin' with that switch?" he bawled in surprise. "Han't
I told you--"

Then he saw the set expression of Azuma-zi's eyes as the Asiatic came
out of the shadow towards him.

In another moment the two men were grappling fiercely in front of the
great dynamo.

"You coffee-headed fool!" gasped Holroyd, with a brown hand at his
throat. "Keep off those contact rings." In another moment he
was tripped and reeling back upon the Lord of the Dynamos. He
instinctively loosened his grip upon his antagonist to save himself
from the machine.

The messenger, sent in furious haste from the station to find out what
had happened in the dynamo shed, met Azuma-zi at the porter's lodge by
the gate. Azuma-zi tried to explain something, but the messenger could
make nothing of the black's incoherent English, and hurried on to the
shed. The machines were all noisily at work, and nothing seemed to be
disarranged. There was, however, a queer smell of singed hair. Then
he saw an odd-looking crumpled mass clinging to the front of the big
dynamo, and, approaching, recognised the distorted remains of Holroyd.

The man stared and hesitated a moment. Then he saw the face, and shut
his eyes convulsively. He turned on his heel before he opened them, so
that he should not see Holroyd again, and went out of the shed to get
advice and help.

When Azuma-zi saw Holroyd die in the grip of the Great Dynamo he had
been a little scared about the consequences of his act. Yet he felt
strangely elated, and knew that the favour of the Lord Dynamo was upon
him. His plan was already settled when he met the man coming from the
station, and the scientific manager who speedily arrived on the scene
jumped at the obvious conclusion of suicide. This expert scarcely
noticed Azuma-zi, except to ask a few questions. Did he see Holroyd
kill himself? Azuma-zi explained he had been out of sight at the
engine furnace until he
