The Box With Broken Seals by E. Phillips Oppenheim

Crawshay walked slowly along the deck until he found a completely sheltered spot. Then he summoned the deck steward and superintended the arrangement of his deck chair, which was almost hidden under a heap of rugs. He had just adjusted a pair of spectacles and was preparing to settle down when Katharine, in her nurse's uniform, issued from the companionway and stood for a moment looking about her. Crawshay at once raised his cap.

"Good morning, Miss Beverley," he said. "You do not recognise me, of course, but my name is Crawshay. I had the pleasure of meeting you once at Washington."
