Season 1 is free: thirteen weekly cases, one cold case after hours. Every grid solves from the statements alone.
Eight years ago a mother of four walked out of a church parking lot in New Halstead, New Jersey, and was never seen again. Her car was right where she left it. Her phone was on the seat. The detective who caught the case has solved every major case he has ever worked, except this one.
You are the new kid. First morning as a junior detective in Lehigh Falls, Pennsylvania, assigned to Det. Thomas Blake: twenty-two years on the job, a cracked Timex, and a silence you will spend a long time learning to read. Two cases later, over bad coffee, he tells you about Jackie Jefferson. Then he tells you to forget it.
You won't.
EVERY DAY IS A CLUE. EVERY WEEK IS A CASE.
Detective Thomas Blake is a logic-puzzle game told as a case file. Each day brings a new deduction grid built from the evidence: witness statements, receipts, timelines, alibis that almost hold. Every grid solves from the statements alone. No guessing, ever.
- Monday to Saturday: work the week's case one file at a time.
- Thursday: a bonus file that earns the key clue. Skip it, and Sunday gets harder.
- Sunday: rebuild the week and name who, why and how.
- Overtime: close a whole week in one sitting and the department notices.
AFTER HOURS
When the squad room empties, you open the old Jefferson file. Nobody asked you to. You read the statements Blake's team took eight years ago and you start to notice things: a tip logged as a crank call, a phone number that leads nowhere, a question nobody thought to ask.
A MYSTERY THAT REMEMBERS THE PEOPLE INSIDE IT
Blake is gruff, dry and very good at his job, and he is carrying more than one unsolved case. The Jefferson family has waited eight years for someone to listen. Your own past brought you to this job too.
SEASON 1 IS FREE
Thirteen weeks of cases, every one solvable without a purchase. Three free hints a day. Optional: Remove Ads, a one-time purchase. Ads appear between cases, never before your first puzzle, never more than one every ten minutes.
Detective Thomas Blake is fiction: all characters, places and events are invented.
The question the game asks on every page: what did everyone miss?
Your shift starts Monday.
