How to catch a culprit

A few minutes, a handful of clues, and one very guilty party.

  1. Step 1: Round up the suspects.

    Everyone was somewhere. Put each one on the map, one to a row and one to a column. Nobody gets to hide.

  2. Step 2: Check their stories.

    Pip swears she was beside the teacup. Every clue means exactly one thing, so the lies run out fast.

    “Pip is beside a teacup.”

  3. Step 3: Name the culprit.

    Place the last suspect and the truth comes out: who was alone with Lord Wren, which cat really pushed the vase, or which plant Sid got to.

The clues never lie, and you'll never have to guess. One case, one culprit, every time.

Three scenes of the crime

A manor, a café and a garden, each with its own regulars and its own bad habits. About one new world arrives each season.

Murder mystery

Lord Ambrose Wren has been murdered. Again. Someone at Ashcombe keeps doing his lordship in, and every guest has a reason. One of them was alone with him when the clock stopped.

The vase didn't fall. It was pushed. The vase is on the floor again and the last macaron is gone. Miso is washing a paw far too casually, Duchess won't meet your eye, and there are crumbs on Pepper's whiskers.

Garden

Sid the slug strikes again. Every case, one prize plant turns up nibbled, and Sid has a shiny trail and no alibi. Work out where Basil, Chamomile, Dahlia and Lavender are planted, and you'll know which one he got to.
