In the early morning of an autumn day, three men commit a crime on the banks of an idyllic lake. Later, one of them will report what happened during the course of that night – claiming he was entirely passive throughout the events, that he simply went along with the others. September Lightning is a novel about the archaic dynamics of fear and violence, and at the same time it is an irresistible crime thriller that keeps the reader hooked from the first page to the last. Kron bumps into Vanek, an acquaintance, in town. Vanek and his friend Gerland persuade Kron to join them for a fun evening trip to the lake, along with another man. But as they drive to the lake: Vanek and Gerland start bullying the other man and he makes no moves to defend himself. Once at the lake, they get more and more drunk, and their malice turns into overt violence. Kron joins in, initially for fear of becoming the next target. But when the victim's passivity strikes him as ever more aggravating, he increasingly participates willingly. On being questioned by the police the next day, he stolidly claims he is not aware of having done anything wrong.
"Martin Gülich kindles a gruesome kind of pleasure in the reader. The conciseness, precision and economy of his writing are the marks of his remarkable skill." (Bavarian Broadcasting Corporation)
