"They are—clumsy ones."

"By any chance are they any of the gentlemen who have been following you?"

"Exactly. Both have had several shots at me."

"That is interesting. The address they left with the military authorities is the Boule d'Argent.

"What I have found out is this: the Cabaret de Biribi has been closed and sealed up by the police; the café remains open. A waiter in the café thought he saw Philippa at the window of her apartment over the cabaret just before noon today.

"But Wildresse, they all say, went away this morning and has not returned. And they have no idea when to expect him.

"Now, my theory is this: Wildresse and his ruffians, realizing that their own necks are in danger, went to Saïs to see Philippa, either to bully her into silence or persuade her to return to duty. When they saw her by the roadside they changed their plans and took a chance. I don't believe they saw us. We were on our knees in the grass under the shadow of the hedge. After they caught her they never looked around. I don't believe any of them noticed us at all. Before the car reached Ausone they must have stopped in some deserted place, found a boat somewhere, sent the car on ahead to Ausone with only two men in it, and then Wildresse and the other two men must have dragged or carried Philippa across the fields to the river and forced her into the boat. That was the only way they could have ventured to enter Ausone. They must have gone by boat to the garden behind the cabaret, where nobody could see what was going on, and there they probably let themselves into the house by the rear entrance.

"That's my theory, Halkett. I believe Philippa is there. I believe Wildresse is there. And I feel very sure that those two choice scoundrels of his at the Boule d'Argent will join him wherever he is. So I think we had better tie up our boat and go to the Boule d'Argent and find these fellows, Meier and Hoffman, and never let them out of our sight."

"I think so, too," said Halkett quietly.

He knelt down on the grass, passed the boat chain around the base of the willow tree, linked and padlocked it, sprang to his feet, and walked quickly after Warner, who had already started to enter the Impasse d'Alcyon.
