In Galloway, one of the most picturesque places in the south of Scotland, where Lord Peter Wimsey often loved to relax, under very strange circumstances an artist falls off a cliff. Wimsey tries many times to imagine how he takes the fatal step, stumbles and flies down. But he can't. Although at first glance it all looks like suicide, Peter Wimsey has good reasons to doubt it. Six people come under suspicion, and not one of them feels regret for the death of his comrade... Five of them are innocent.
