About

What Is This?

Whodunnit Weekly is a weekly interactive murder mystery puzzle. Each week, a new case is published with a full set of investigation documents — autopsy reports, witness statements, forensic evidence, newspaper clippings, and more. Your job is to read the evidence, study the suspects, and work out whodunnit.

How Do I Play?

Each case page presents all the evidence you need. Read through the documents carefully — every detail could be a clue (or a red herring). When you think you've cracked it, visit the solution page to see if you were right. The solution includes the identity of the killer, their method and motive, and a step-by-step chain of reasoning.

Eras

Cases span five historical eras, each with its own flavour and investigative challenges:

Victorian Gas-lit drawing rooms, arsenic, and unreliable servants
1920s Country house weekends, cocktail-hour poisonings, and sharp-eyed butlers
1940s Wartime secrets, blackout alibis, and rationed motives
1970s Office politics, suburban tensions, and forensics on the rise
Modern Digital evidence, CCTV timelines, and social media trails

Difficulty

Cases are rated from 1 to 5 diamonds. A one-diamond case has fewer suspects and more obvious clues. A five-diamond case has many suspects, contradictory evidence, and subtle red herrings designed to mislead even experienced detectives.

How Are Cases Made?

Each case begins with a real historical crime — the era, the method, the investigative techniques of the time. From there, we build a complete fictional mystery with original characters, evidence, and documents. Every case is unique, and every case is solvable.

Who Made This?

Whodunnit Weekly is created by AG Barnett, a mystery author based in Oxfordshire with 15 published novels across five series including the Brock & Poole Mysteries, the Mary Blake Mysteries, and the Hammond & Circle Mysteries. Each case draws on the same plotting techniques behind his books — layered suspects, fair clues, and satisfying solutions.
