Tom Barber Hillford writes comedy and crime, often at the same time. A lifelong fan of puzzles, twisty timelines, and the particular joy of yelling "I knew it!" at a television at eleven at night, Hillford has spent years absorbing true crime documentaries and forensic procedurals with the same devotion most people reserve for their favorite sitcom.That fascination is the engine behind every case file Hillford builds: real evidence, real logic, and a solution that was fair all along, if the reader knew where to look.Who Took the Diamond? is Hillford's latest case file for readers who would rather solve the mystery than just watch it unfold.
