And Rogers, he gets the wind up too and bumps off his wife! All according to U.N.O.'s plan."
Armstrong shook his head.
He stressed the point about the Cyanide.
Blore agreed. "Yes, I'd forgotten that.
Not a natural thing to be carrying about with you.
But how did it get into his drink, sir?"
Lombard said: "I've been thinking about that.
Marston had several drinks that night.
Between the time he had his last one and the time he finished the one before it, there was quite a gap. During that time his glass was lying about on some table or other.
I think - though I can't be sure, it was on the little table near the window.
The window was open.
Somebody could have slipped a dose of the Cyanide into the glass."
Blore said unbelievingly: "Without our all seeing him, sir?"
Lombard said drily: "We were all - rather concerned elsewhere."
Armstrong said slowly: "That's true. We'd all been attacked.
We were walking about, moving about the room. Arguing, indignant, intent on our own business.
I think it could have been done..."
Blore shrugged his shoulders.
"Fact is, it must have been done!
Now then, gentlemen, let's make a start.
Nobody's got a revolver, by any chance?
I suppose that's too much to hope for."
Lombard said: "I've got one." He patted his pocket.
Blore's eyes opened very wide.
He said in an over-casual tone: "Always carry that about with you, sir?"
Lombard said: "Usually.
I've been in some tight places, you know."
"Oh," said Blore and added: "Well, you've probably never been in a tighter place than you are today!
If there's a lunatic hiding on this island, he's probably got a young arsenal on him - to say nothing of a knife or dagger or two."
Armstrong coughed.
"You may be wrong there, Blore.
Many homicidal lunatics are very quiet, unassuming people.
Delightful fellows."
Blore said: "I don't feel this one is going to be of that kind, Dr. Armstrong."
II The three men started on their tour of the island.
It proved unexpectedly simple.
On the northwest side, towards the coast, the cliffs fell sheer to the sea below, their surface unbroken.
On the rest of the island there were no trees and very little cover.
The three men worked carefully and methodically, beating up and down from the highest point to the water's edge, narrowly scanning the least irregularity in the rock which might point to the entrance to a cave.
But there were no caves.
They came at last, skirting the water's edge, to where General Macarthur sat looking out to sea.
It was very peaceful here with the lap of the waves breaking over the rocks. The old man sat very upright, his eyes fixed on the horizon.
He paid no attention to the approach of the searchers.
His oblivion of them made one at least faintly uncomfortable.
Blore thought to himself:
"'Tisn't natural - looks as though he'd gone into a trance or something." He cleared his throat and said in a would-be conversational tone:
"Nice peaceful spot you've found for yourself, sir."
The General frowned. He cast a quick look over his shoulder.
He said: "There is so little time - so little time. I really must insist that no one disturbs me."
Blore said genially: "We won't disturb you.
