I idled about the hotel, impatient and angry with myself. Yes, Rayner was right after all! I ought to have made some effort to follow the three men. But now, it was quite impossible. They were, no doubt, far away, and probably old Gregory's treasure was by that time safe in his own hands.

The evidence of the shoe puzzled me. The wearer of that little shoe with the two pearl buttons had, without doubt, been near that seat on the East Cliff where Craig had been killed—present, in all probability, when he had been so mysteriously stricken down.

Was it possible that a woman—the same woman—had assisted in the burglary, and had inadvertently lost her shoe? Perhaps she had taken her shoes off in order to move noiselessly, and in trying to recover them could only regain one!

Lola, I remembered, possessed a very small foot. She was always extremely neat and dainty about the ankles and wore silk stockings and pretty shoes. Was it the print of her foot that I had found near that fatal seat? Was it her shoe that had been found at Beacon House?

Ah! If I could but see her? If she would only call upon me once again!

Day after day I waited, but, alas, she did not come.

That she was most anxious to see me was proved by the fact that she had dared to call at all after what had occurred. She had some strong motive in meeting me again, therefore I lived on in hope that she would return.

The Nightingale! Heavens! What strange memories that one word brought back to me as I sat in the window of my high-up room, gazing over the summer sea.

It was now July, and Cromer was rapidly filling with better-class folk. Now and then I went to London, but only for the day, fearing lest Lola should send me a telegram to meet her. In my absence Rayner always remained on duty.

I had written to her address in the Avenue Pereire, in Paris, but had received no reply. Then I had sent a line to the concierge of the house wherein the flat was situated. To this I had received an ill-scribbled few lines in French, expressing a regret that Mademoiselle had vacated the place some weeks previously and that her present address was unknown.
