A minute can make all the difference...Pieter Posthumus is enjoying a quiet drink in his favourite bar when the screaming starts. A minute later, the owner of the guesthouse next door rushes in: one of her tenants has been murdered. Marloes, the guesthouse owner, is an odd but kind soul. Posthumus cannot believe it when she is arrested - for both her tenant Zig's murder and another death years before. He knows there are questions unanswered: what is the link between the two cases? Why are people so keen to think Marloes is guilty? And why did Zig paint just one picture every year - a copy of a Dutch master, but with one peculiar twist? As his investigation progresses, he comes to see that a few minutes can mean all the difference in the world: between saving a life and taking one; between innocence and guilt. And that sometimes asking questions leads to a truth that's hard to bear.
