"There are only four of them."

"If they call out?"

"They won't call out."

"If Altenheim returns?"

"He won't return before ten o'clock. I'll see to it. That gives you two hours and a half, which is more than you require to explore the house from top to bottom. If you find old Steinweg, come and tell me."

Baron Altenheim came up. Sernine went to meet him:

"Let's have some dinner, shall we? That little incident in the garden has made me feel hungry. By the way, my dear baron, I have a few bits of advice to give you. . . ."

They sat down to table.

After dinner, Sernine suggested a game of billiards. Altenheim accepted. When the game was over, they went to the baccarat-room. The croupier was just shouting:

"There are fifty louis in the bank. Any bids?"
