这是个低气压增强、春天里少见的雷鸣之夜。当独身生活的推理小说作家在公寓的房间里写作时,被人突然从背后刺了一刀而身亡。第二天,尸体被发现时,写字台上的荧光台灯还亮着。这是一台没有起动器的简易日光灯。但奇怪的是, 写字台上放着的一只手电筒也是亮着的。 This is a low pressure, rare thunder in the spring night. When a cynical writer of celibacy writing in the apartment's room, she was suddenly stabbed from the back and killed. The next day, when the body was found, the fluorescent desk lamp on the desk was lit. This is a simple fluorescent lamp without a starter. But it is strange that a flashlight on the desk is also lit.
