Two days after this minor puzzle, which to its credit had sufficiently stimulated my brain to bring me slightly out of my lethargy, I noted one of Lestrade's men slogging through the rain - which had not stopped since Watson lost his watch - coming up the walk towards 221 Baker street.

"Ah," I remarked lightly to Watson, "It seems I was mistaken about Scotland Yard's dedication to your pocket-watch."

Watson brightened up immediately - he had till now been mourning his timepiece - and there was a spark of hope in his eyes as Mrs. Hudson showed the visitor up to our door.

"Ah, good afternoon, Gregson," I said as I opened the door, "What brings you here in such hideous weather?"

"Two things, mainly," said he.

"Then perhaps you would like to sit and dry yourself while you talk?" I offered.

Gregson looked a bit pained then as he declined either to sit or to dry his overcoat by the fire, and the cordiality seemed to evaporate from the sitting room as he turned to Watson.

"We found your watch," Gregson announced, though the manner in which this statement was delivered understandably confused my friend.

"Where did you find it?" Watson asked, with due caution, "I trust you found it in good condition?"

"It's fine," Gregson said, "But the thing is, we found it at the scene of the latest burglary."

Watson looked and I felt as though we'd both been slapped.

"So, you understand we need to ask you a few questions, Doctor," Gregson continued, all the while looking as though he were attempting to pass a particularly large and jagged gallstone, "It's all a matter of procedure. Nothing against you personally."

Watson looked at me helplessly, then turned back to Gregson. "I'm sure this is all a big mistake," Watson said to me, "I shouldn't be very long, Holmes. You'll see."

He grabbed an overcoat from the coatrack _en_passe_ as he and Gregson left. My mind was racing, so it was only a matter of seconds before I realised that Watson had grabbed my overcoat by mistake. I grabbed his overcoat and was almost at the door, meaning to call them back and return Watson's overcoat, when I noticed something sparkle in the coat pocket. I stopped short by the door, and felt around in the pocket, pulling out what I found there.

It was a delicate diamond bracelet.
