“No.”

I rang the bell and ordered restoratives.

“Well, Bobbie,” I said, “it’s a pretty hard case to spring on an untrained amateur like me. Suppose someone had come to Sherlock Holmes and said, ‘Mr. Holmes, here’s a case for you. When is my wife’s birthday?’ Wouldn’t that have given Sherlock a jolt? However, I know enough about the game to understand that a fellow can’t shoot off his deductive theories unless you start him with a clue, so rouse yourself out of that pop-eyed trance and come across with two or three. For instance, can’t you remember the last time she had a birthday? What sort of weather was it? That might fix the month.”

Bobbie shook his head.

“It was just ordinary weather, as near as I can recollect.”

“Warm?”

“Warmish.”

“Or cold?”

“Well, fairly cold, perhaps. I can’t remember.”

I ordered two more of the same. They seemed indicated in the Young Detective’s Manual. “You’re a great help, Bobbie,” I said. “An invaluable assistant. One of those indispensable adjuncts without which no home is complete.”
