his hand flew to his breast; there was a silvern gleam and--
"Drop that whistle!" snapped Smith, and struck it from the man's hand.
"Where's your lantern? Don't ask questions!"
The constable started back and was evidently debating upon his chances
with the two of us, when my friend pulled a letter from his pocket and
thrust it under the man's nose.
"Read that!" he directed harshly, "and then listen to my orders."
There was something in his voice which changed the officer's opinion
of the situation. He directed the light of his lantern upon the open
letter, and seemed to be stricken with wonder.
"If you have any doubt," continued Smith--"you may not be familiar
with the Commissioner's signature--you have only to ring up Scotland
Yard from Dr. Petrie's house, to which we shall now return to disperse
it." He pointed to Forsyth. "Help us to carry him there. We must not
be seen; this must be hushed up. You understand? It must not get into
the Press--"
The man saluted respectfully, and the three of us addressed ourselves
to the mournful task. By slow stages we bore the dead man to the edge
of the common, carried him across the road and into my house, without
exciting attention even on the part of those vagrants who nightly
slept out in the neighbourhood.
We laid our burden upon the surgery table.
"You will want to make an examination, Petrie," said Smith in his
decisive way, "and the officer here might 'phone for the ambulance. I
have some investigations to make also. I must have the pocket lamp."
He raced upstairs to his room, and an instant later came running down
again. The front door banged.
"The telephone is in the hall," I said to the constable.
"Thank you, sir."
He went out of the surgery as I switched on the lamp over the table
and began to examine the marks upon Forsyth's skin. These, as I have
said, were in groups and nearly all in the form of elongated
punctures; a fairly deep incision with a pear-shaped and superficial
scratch beneath it. One of the tiny wounds had penetrated the right
eye.
The symptoms, or those which I had been enabled to observe as Forsyth
had first staggered into view from among the elms, were most puzzling.
Clearly enough the muscles of articulation and the respiratory
muscles had been affected; and now the livid face, dotted over with
tiny wounds (they were also on the throat), set me mentally groping
for a clue to the manner of his death.
No clue presented itself; and my detailed examination of the body
availed me nothing. The grey herald of dawn was come when the police
arrived with the ambulance and took Forsyth away.
I was just taking my cap from the rack when Nayland Smith returned.
"Smith!" I cried, "have you found anything?"
He stood there in the grey light of the hall-way tugging at the lobe
of his left ear.
The bronzed face looked very gaunt, I thought, and his eyes were
bright with that febrile glitter which once I had disliked, but which
I had learned from experience to be due to tremendous nervous
excitement. At such times he could act with icy coolness, and his
mental faculties seemed temporarily to acquire an abnormal keenness.
He made no direct reply, but--
"Have you any milk?" he jerked abruptly.
So wholly unexpected was the question that for a moment I failed to
grasp it. Then--
"Milk!" I began.
"Exactly, Petrie! If you can find me some milk, I shall be obliged."
I turned to descend to the kitchen, when--
"The remains of the turbot from dinner, Petrie, would also be welcome,
and I think I should like a trowel."
I stopped at the stairhead and faced him.
"I cannot suppose that you are joking, Smith," I said, "but--"
He laughed dryly.
"Forgive me, old man," he replied. "I was so preoccupied with my own
train of thought that it never occurred to me how absurd my request
must have sounded. I will explain my singular tastes later; at the
moment, hustle is the watchword."
Evidently he was in earnest, and I ran downstairs accordingly,
returning with a garden trowel, a plate of cold fish, and a glass of
milk.
"Thanks, Petrie," said Smith. "If you would put the milk in a jug--"
I was past wondering, so I simply went and fetched a jug, into which
he poured the milk. Then, with the trowel in his pocket, the plate of
cold turbot in one hand and the milk-jug in the other, he made for the
door. He had it open, when another idea evidently occurred to him.
"I'll trouble you for the pistol, Petrie."
I handed him the pistol without a word.
"Don't assume that I want to mystify you," he added, "but the presence
of any one else might jeopardize my plan. I don't expect to be long."
The cold light of dawn flooded the hall-way momentarily; then the door
closed again and I went upstairs to my study, watching Nayland Smith
as he strode across the common in the early morning mist. He was
making for the Nine Elms, but I lost sight of him before he reached
them.
I sat there for some time, watching for the first glow of sunrise. A
policeman tramped past the house, and, a while later, a belated
reveller in evening clothes. That sense of unreality assailed me
again. Out there in the grey mist a man who was vested with powers
which rendered him a law unto himself, who had the British Government
behind him in all that he might choose to do, who had been summoned
from Rangoon to London on singular and dangerous business, was
employing himself with a plate of
