Kellanpunainen timantti

Set in a squalid London quarter, the story follows a young, cash-strapped writer who becomes drawn into a criminal mystery after a dead man and a missing, valuable jewel surface. Investigations pivot on pawned items, two letters and an obscure manuscript, prompting police inquiries and the arrival of private investigators. Leads thread through pawnshops, a private laboratory, teahouses and empty houses while an array of characters — friends, suspects and intermediaries — shift allegiances. Gradually forensic detail, eyewitness memory and strategic questioning reveal how the jewel was handled, who profited, and the scheme behind the death as efforts concentrate on recovering the gem and resolving culpability.
