Logic grid puzzles

Work out who did what from the clues, ticking the grid as you rule things out.

Two things are checked before a puzzle reaches this page. The clues must lead to exactly one answer, and none of them may be redundant: every clue listed is one the puzzle cannot be solved without. Spare clues make a puzzle feel long rather than hard.
