The cards

Pick a person by tapping the photo on their card, the victim too. Then tap a square to put them there, or drag the photo onto it. At this difficulty the game doesn’t cross off rows and columns for you, unless you switch on Cross off for me. Holding a square, or switching the pencil on, makes a note. Keyboard: Enter places, Shift and Enter makes a note.

Good to know

Beside: on one of the four squares directly above, below, left or right, in the same room. Diagonally doesn’t count, and neither does through a wall. A window or door in the wall of your square is beside you.
Alone, or the only person in a room: nobody else in that room, the victim included. Alone with someone: those two, and nobody else in that room.
In a corner: on a square of that room where two of its walls meet. The end of a narrow corridor counts too.
