1899, Glasgow. A man is stabbed to death in a tenement courtyard and Juan Camarón, photographer-cum-sleuth, is enlisted to assist the police investigation. Perhaps his innovative photographic method can bring to light what the naked eye might overlook. Juan is also contending with his own problems. His late father''s legacy, a monumental photographic record of Cuban architecture, faces a charge of plagiarism from a mysterious señora. And Jane, his fiancée, is witnessed fleeing the scene of a murder. Juan''s hoped-for happiness is threatened and he is torn between finding the killer and finding Jane. But could they be one and the same?
