"At the start of Alexander’s enchanting sixth late Victorian novel of suspense (after 2010’s Dangerous to Know), news of a fire in Southwark prompts British intelligence agent Colin Hargreaves to leave Lady Londonderry’s ball, to his wife Emily’s dismay. Colin returns home to Mayfair that night to announce that Michael Dillman, who ran a successful export business, has been cruelly burned alive in his warehouse by an unknown perpetrator. The week before, according to Michael’s fiancée, someone threw red paint on his front door. The Sanders family receives similar treatment shortly before the rumor breaks that daughter Polly’s mother was, in fact, a maid impregnated by her father. Subsequently, other respectable London families find red paint splashed on their houses, presaging some scandalous revelation in each case. Can Emily help Colin solve the crimes without risking her reputation—or becoming a target herself? Alexander keeps readers guessing to the very end."
