Winnie Achterberg is sixty-three, retired, and almost certain that the small harbour picture hanging in the city museum is not the one she restored thirty-one years ago. Almost. She has no proof, and nobody who would listen.

So she gathers a few people who owe her nothing: an old locksmith with a bad hand, a night cleaner who knows every corridor, a photographer who sees too much, a forger of the gentlest kind. Together they write rules. Nobody gets hurt. Nothing is taken. No money changes hands. If they are caught, they tell the truth.

Then the gala night comes, and the rules begin to cost them.

The Honest Heist is a warm, dry, slow-building caper about friendship, memory, and how hard it is to do the right thing in exactly the right way.
