“Have you anything to say before you are put to death as a spy?”

“Simply lots of things,” replied Tommy with the same urbanity as before.

“Do you deny that you were listening at that door?”

“I do not.  I must really apologize—­but your conversation was so interesting that it overcame my scruples.”

“How did you get in?”

“Dear old Conrad here.”  Tommy smiled deprecatingly at him.  “I hesitate to suggest pensioning off a faithful servant, but you really ought to have a better watchdog.”

Conrad snarled impotently, and said sullenly, as the man with the beard swung round upon him: 

“He gave the word.  How was I to know?”

“Yes,” Tommy chimed in.  “How was he to know?  Don’t blame the poor fellow.  His hasty action has given me the pleasure of seeing you all face to face.”

He fancied that his words caused some discomposure among the group, but the watchful German stilled it with a wave of his hand.

“Dead men tell no tales,” he said evenly.

“Ah,” said Tommy, “but I’m not dead yet!”

“You soon will be, my young friend,” said the German.

An assenting murmur came from the others.

Tommy’s heart beat faster, but his casual pleasantness did not waver.

“I think not,” he said firmly.  “I should have a great objection to dying.”

He had got them puzzled, he saw that by the look on his captor’s face.

“Can you give us any reason why we should not put you to death?” asked the German.

“Several,” replied Tommy.  “Look here, you’ve been asking me a lot of questions.  Let me ask you one for a change.  Why didn’t you kill me off at once before I regained consciousness?”

The German hesitated, and Tommy seized his advantage.

“Because you didn’t know how much I knew—­and where I obtained that knowledge.  If you kill me now, you never will know.”

But here the emotions of Boris became too much for him.  He stepped forward waving his arms.

“You hell-hound of a spy,” he screamed.  “We will give you short shrift.  Kill him!  Kill him!”

There was a roar of applause.

“You hear?” said the German, his eyes on Tommy.  “What have you to say to that?”

“Say?” Tommy shrugged his shoulders.  “Pack of fools.  Let them ask themselves a few questions.  How did I get into this place?  Remember what dear old Conrad said—­with your own password, wasn’t it?  How did I get hold of that?  You don’t suppose I came up those steps haphazard and said the first thing that came into my head?”

Tommy was pleased with the concluding words of this speech.  His only regret was that Tuppence was not present to appreciate its full flavour.

“That is true,” said the working man suddenly.  “Comrades, we have been betrayed!”

An ugly murmur arose.  Tommy smiled at them encouragingly.
