The servant in the doorway was pushed suddenly aside, and a short spherical man elbowed his way unceremoniously past him into the room.

“I am Inspector Kleinhaus, of the police,” he said, “and I should also like to hear the answer to that.”

“You see,” he explained diffidently, “we had a friendly tip from Italy that two known Italian criminals had bought tickets to Switzerland. It was my job to keep an eye on them. I’m afraid they gave me the slip last night, for long enough to attack and rob Signor Ravenna. When I met you at the scene of the crime, Mr Tombs, I didn’t know if you might be associated with them, so I didn’t introduce myself completely. But we kept watch on you. We saw you find the briefcase and take it to your room — incidentally, we recovered it as soon as you went out, with its interesting contents.”

Galen put the automatic in his pocket and took out the necklace.

“Except this,” he said conscientiously.

“Thank you,” said Kleinhaus. “Meanwhile, Mr Tombs, we went on keeping an eye on you, to see where you’d lead us. I still didn’t know how deeply you were involved in the affair, and I was as puzzled as you seem to have been by the things Ravenna was carrying and by the motive for the robbery. Most of that has now been cleared up. One of my men followed you here, and I followed Signora Ravenna myself after I talked to her at the police station a little while ago. Her answers seemed as suspicious to me as they apparently did to you.”

“How long have you been listening?” Simon asked.

“Monsieur Galen’s servant was too agitated by the way Signora Ravenna behaved when he told her her husband was already here to remember to shut the front door, so I’ve been in the hall all the time. It was very illuminating.” The detective’s bright blue eyes shifted again. “Now, Signora Ravenna, I still want to hear what you were going to say.”

Her face was a white mask.
