The Penthouse
Case #001 · EasyThe Penthouse

Three people were inside. All three hide something. Only one killed him.

The Understudy
Case #002 · EasyThe Understudy

Opening night. The star finished act one and never made it to act two.

Low Tide
Case #003 · MediumLow Tide

The sea returned a man who never went into it.

The 37th Floor
Case #004 · HardThe 37th Floor

Everyone in the building heard the shot. Nobody heard the elevator.

The Silent Metronome
Case #005 · EasyThe Silent Metronome

The metronome was still ticking when they found her. But the music had stopped.

The Winning Ticket
Case #006 · EasyThe Winning Ticket

Last week he sold the jackpot ticket — 1.4 million. Nobody claimed it. Nobody walks away from that money. Unless claiming it would give them away.

Terminal 4
Case #007 · MediumTerminal 4

His sealed case left at 2,300 grams and arrived at 2,000. The seal is intact. Seals do not lie — people with seal tools do.

The Beekeeper
Case #008 · MediumThe Beekeeper

He died from bee venom, but he has no stings. And his hives now stand three meters from where they stood all summer. Dead men do not move hives.

Two Grooms
Case #009 · HardTwo Grooms

The engraved toast glasses moved twice tonight. The man who died was never the target.

The Night Librarian
Case #010 · EasyThe Night Librarian

In thirty-one years she never misplaced a book. On her last night, one book sat on the wrong shelf.

Cold Open
Case #011 · MediumCold Open

He died on live TV. The station cut to the weather, and everyone watching saw him fall.

The Allotment
Case #012 · EasyThe Allotment

Eight weeks of no rain, yet on Plot 11 a rain barrel is full to the top. That isn't water. It's a hiding place.

Last Cable Car
Case #013 · HardLast Cable Car

Five people went up on the last car. Four came down. The mountain can't count, so somebody counted for it.

The Food Critic
Case #014 · MediumThe Food Critic

The tasting log is clear — no food served was poisoned. Julian chewed his pens for thirty years, and one person in that kitchen remembered.

Grave Shift
Case #015 · HardGrave Shift

Every clock on the ward runs seven minutes fast. That is the whole case.

The Hothouse
Case #016 · MediumThe Hothouse

Frost on the inside of the glass in high summer. No wounds, no poison — just one hour of air with almost no oxygen in it.

Second Chair
Case #017 · EasySecond Chair

The murder weapon is knowledge. Exactly three people knew about his allergy. The case is a countdown from three.

Paper Boats
Case #018 · MediumPaper Boats

Nineteen paper boats in the reeds — and the twentieth still dry in his coat, dated tomorrow.

The Ninth Hole
Case #019 · EasyThe Ninth Hole

The sand on his clothes is fine white silica. The ninth hole uses coarse river sand. He was moved.

Open House
Case #020 · MediumOpen House

The staging list has 214 rented items. The house holds 215. The killer brought the extra one in — the weapon.

The Understory
Case #021 · HardThe Understory

The broken seam was re-sewn by a patient hand — with upholstery thread, not climbing thread. Someone sewed him an accident.

The Cold Room
Case #022 · EasyThe Cold Room

The cave keeps everything at ten degrees — the cheese, the truth, the body. The door only locks from outside.

Radio Silence
Case #023 · MediumRadio Silence

Every night at three he played one song and said nothing for four minutes thirty-three seconds. Somebody set a watch by his silence.

The Pilot Light
Case #024 · MediumThe Pilot Light

A gas leak, sealed windows, an open valve — and a canary singing loudly three feet from the body.

Still Life
Case #025 · HardStill Life

She cleaned paintings for thirty years. The one on her easel was cleaned twice in one night. The second time hid what the first found.

The Last Ferry
Case #026 · MediumThe Last Ferry

His logbook says he made the 2:15 crossing on calm water. But the tide table says the channel was dry mud at that hour. One of those books is lying.

Night Market
Case #027 · EasyNight Market

His scale was the only honest one in the market. Now it lies by exactly forty grams. Scales don't do that alone. Someone changed it.
