He turned and pointed to the dead body which lay full in view from where we were seated. Gerard let his eyes follow the gesture and withdrew them with a sickly twinge.

“Everyone knew it, I think. It was the disguise he wore invariably in the club. It was as if he came here to meet his clients, and it was necessary for them to know that they were speaking to him.”

Sir Frank Tarleton nodded more than once this time. He evidently felt himself to be getting a firm grip on the problem. I admired the sagacity he had shown in transferring his examination from the proprietress of the club to the waiter. Gerard was proving a much easier witness to deal with than Madame Bonnell. He had not so much at stake.

“And now,” the consultant pursued, “perhaps you can tell us if there were any other persons who showed a desire to meet Wilson last night?”

Gerard brightened up visibly.

“But certainly, milor. There was one in particular who never seemed to take her eyes off him. She danced with him time after time, and when she was not dancing with him herself she watched those who did.”

“And how was she dressed?”

“Milor, she was hardly dressed at all.” Gerard may have feared another irreverent guess from Captain Charles, for he added quickly: “I heard Monsieur address her as Salome.”

The Inspector was again busy with his note-book. But Sir Frank struck me as not being quite so deeply interested in Salome as he had been in Zenobia.

“And there was also a lady whose costume it is not easy to describe.” Gerard was going on of his own accord now, as though his interest had been kindled in the inquiry. “Part of it was a leopard skin. And she wore a necklace composed of claws of the same beast, as I imagined. In my own mind I called her the Leopardess. Without doubt, her costume was that of an East Indian princess.”
