tter say nothing. Also with the theft of
certain papers known to have been in his possession."

Now it is possible that at this precise moment Marnstam would have made
his spring for the window and Rounceby his running fight for liberty.
The hands of both men were upon their revolvers, and John Dory's life
was a thing of no account. But at this juncture a thing happened. There
were in the room the two policemen guarding the swing doors, and behind
them the pale faces of a couple of night porters looking anxiously in.
Vincent Cawdor and Miss Brown were standing side by side, a little in
the background, and the young man who had been their companion had risen
also to his feet. As though with some intention of intervening, he moved
a step forward, almost in line with Dory. Rounceby saw him, and a new
fear gripped him by the heart. He shrank back, his fingers relaxed
their hold of his weapon, the sweat was hot upon his forehead. Marnstam,
though he seemed for a moment stupefied, realised the miracle which had

"You say that your name is Victor Franklin?" he asked.

"Certainly!"

"I am."

"You were in Westmoreland with these two men a few days go?"

"I was," the young man admitted.

"You left the village of Scawton in a motor car with them?"

"Yes! We quarrelled on the way, and parted."

"You were robbed of nothing?"

Victor Franklin smiled.

"Certainly not," he answered. "I had nothing worth stealing except my
plans, and they are in my pocket now."

There was a few moments' intense silence. Dory wheeled suddenly round,
and looked to where Mr. Vincent Cawdor had been standing.

"Where is Mr. Cawdor?" he asked, sharply.

"The gentleman with the grey moustache left a few seconds ago," one of
the men at the door said. Dory was very pale.

"Gentlemen," he s
