Long before I reached Aunt Agatha’s lair I could tell that the hunt was up. Divers chappies in hotel uniform and not a few chambermaids of sorts were hanging about in the corridor, and through the panels I could hear a mixed assortment of voices, with Aunt Agatha’s topping the lot. I knocked but no one took any notice, so I trickled in. Among those present I noticed a chambermaid in hysterics, Aunt Agatha with her hair bristling, and the whiskered cove who looked like a bandit, the hotel manager fellow.

“Oh, hallo!” I said. “Hallo-allo-allo!”

Aunt Agatha shooshed me away. No welcoming smile for Bertram.

“Don’t bother me now, Bertie,” she snapped, looking at me as if I were more or less the last straw.

“Something up?”

“Yes, yes, yes! I’ve lost my pearls.”
