Unsolved HQ — Every clue matters.
EVERY CLUE MATTERS

For the relentlessly curious.

Unsolved HQ is a home for people who notice the detail, question the obvious and never quite accept the easy answer.

We’re building free interactive detective cases where you examine evidence, interrogate suspects and piece together the truth. Our first assignment is Case Zero — The Last Train to London.

Beyond the case files, you’ll find guides and a developing selection of mystery games to bring the investigation to your own table.
