"Well, I am going to offer you a little sensation, though it always greatly affects me. Everything is just right for it, and I am in the humor, too."

"What is it to be?" asked Count Kallash indifferently.

"You will see in a moment. Do you know that there are underground canals in St. Petersburg?"

"In St. Petersburg?" asked Kallash in astonishment.

"Yes, in St. Petersburg! A whole series of underground rivers, wide enough for a boat to pass through. I have rowed along them several times. Does not that offer a new sensation, something quite unlike St. Petersburg?"

"Yes, it is certainly novel," answered Count Kallash, now interested.
"Where are they? Pray show them to me."

"There is one a few yards off. Shall we enter? You are not afraid?" she said with a smile of challenge.

"By no means—unless you command me to be afraid," Kallash replied in the same tone. "Let us enter at once!"

"Kasimir, turn under the arch!" and the boat cut across the canal toward a half circle of darkness. A moment more and the darkness engulfed them completely. They were somewhere under the Admiralty, not far from St. Isaac's Cathedral. Away ahead of them was a tiny half circle of light, where the canal joined the swiftly flowing Neva. Carriages rumbled like distant thunder above their heads.

"Deuce take it! it is really rather fine!" cried the count, with evident pleasure. "A meeting of pirates is all we need to make it perfect. It is a pity that we cannot see where we are!"
