内容简介：
It's nearing the end of World War II, and Michael Harcsh has been working for the government on a secret project for years. Finally, he is ready to hand over his precious formula. But the next morning, he is found dead, shot in the church where he used to go and play the organ. It looks like suicide, but Sir George Rendel believes otherwise. But when the police nail the wrong man, there's nothing for it but to bring in Miss Silver...much to the chagrin of Chief Inspector Lamb.
