"I hope to be the ray of sunshine to light you out of this prison," said Gaillard.

"I'm afraid that will be a difficult matter," replied Tournay. "I am not so clever as you in wearing disguises."

"You will wear no disguise," answered Gaillard. "Are you in a cell by yourself?" he asked in the next breath.

"No, strange to say I have a companion, Citizen St. Hilaire."

"That is not so bad; only we shall have to include him in our plans," replied Gaillard. "You can trust him?"

"Implicitly."

"When I lean forward over my stick," said Gaillard, "run your hand stealthily up the back of my head under my long hair. Now."

Tournay did as he was bid.

"Do you feel it?"

"I feel something hard, like a little file."
