The Pouch in the Alley
Picture a gem exposition, tables lined with velvet trays, dealers murmuring over loupes. Mrs. Emery’s table held her usual mix: aquamarines, a handful of so-so sapphires, garnets, bloodstones, and the piece she was proudest of, a flawless emerald.
Then came the noise. A minor traffic accident outside pulled the whole room toward the windows and out the door, Mrs. Emery included. It took maybe a minute. When she turned back, her entire display was gone.
Police found a pouch in an alley two blocks away. Inside: the sapphires, the garnets, the aquamarines, the bloodstones. Every stone, in fact, except the emerald. Before you read on, sit with that detail. The answer to who took it is already in front of you.
Why Dump the Loot?
Here’s the problem a police captain might wave away and a careful reader shouldn’t. Someone staged a distraction, grabbed a full tray of unmounted gems, and ran. That’s not a casual grab. That takes planning.
So why would a planner, having pulled off the hard part, then toss away most of what they stole? A panicked opportunist keeps everything, because in a rushed getaway and bad light, loose stones all look roughly the same. A panicked opportunist doesn’t keep everything either, because panic drops things, it doesn’t sort them.
What actually happened was neither. Four kinds of stone got left behind on purpose. One stone got kept on purpose. That’s not panic. That’s a decision made in seconds, by someone who already knew exactly what they were looking at.
What It Takes to Spot a Real Emerald
Try this for a second: hand someone five unmounted stones in dim light and ask them to grab only the valuable one. Most people couldn’t do it fast. A fine emerald isn’t obvious at a glance the way a diamond’s sparkle is. You’re reading color saturation, clarity under inclusions, how the cut was handled, and what all of that actually commands on the market, and you’re doing it in seconds, under stress, without a loupe.
That’s not a skill a random thief has. It’s a skill a gem dealer has. Mrs. Emery landed on the same conclusion: whoever discarded four categories of stone while keeping exactly the emerald had to already know gems the way she did. Which meant the thief hadn’t come in off the street. The thief had been standing in the room the whole time.
Three Dealers, One Giveaway
Only a handful of people fit that description: the other dealers at the exposition. Rodney Dipp, in from Boston, was dressed in polyester that looked a decade out of fashion. Julia Kidd, from Atlanta, had shown up in sneakers and a jogging suit. Klaus Braun, from Düsseldorf, was normally the sharpest dresser in the room, except that day he was wearing one brown sock and one blue one.
Three dealers, three odd wardrobe choices. Only one of those choices is actually a clue. Before the next section, take a guess. Who grabbed the emerald?
The Mind Behind the Mystery
This case comes from Hy Conrad, published as part of The Little Giant® Book of Whodunits (co-written with Matt LaFleur, Sterling Publishing, 1998), and later shared on Neatorama on May 25, 2015. Conrad spent all eight seasons as one of the original writers on the TV series Monk, the final two as Co-Executive Producer, work that earned the show three Edgar Nominations from the Mystery Writers of America. He’s also written hundreds of short stories and ten books of short whodunits, sold in fourteen languages.
What ties it together is a style of mystery that isn’t interested in shock. Monk solved cases by noticing the one thing in a room that didn’t match. Conrad’s puzzles work the same way: every clue needed to solve the case fairly is already on the page, no hidden information, nothing pulled out of nowhere at the end.
The Detail Everyone Else Skims Past
The published version of this puzzle keeps its actual answer tucked behind a “reveal” link, so what follows is this article’s own attempt at solving it with the clues on the table, not a confirmed answer straight from the source. Read it as the logic the puzzle invites, not as a verdict.
With that caveat in place: Klaus Braun. A man described as normally stylish doesn’t show up to a professional event with one brown sock and one blue one by accident. People who care about their appearance don’t make that mistake unless their mind is somewhere else entirely, somewhere more urgent than matching an outfit. Like, say, staging a diversion and sorting through a tray of stones in an alley before the police arrive.
Dipp’s outdated polyester and Kidd’s jogging suit are just personality. Braun’s socks are a contradiction, a man usually careful being careless, and that gap is the detail the logic points to.
That’s the real skill this puzzle is testing, and it’s the same one Mrs. Emery used on the gems themselves: not more information than anyone else, just the habit of clocking the detail that doesn’t fit the pattern, and asking why.
