Suddenly at His Residence (1946), also published as The Crooked Wreath, is a quintessential Golden Age detective novel by Christianna Brand, featuring her beloved sleuth, Inspector Cockrill. Set in a stately English country house during wartime, the novel blends intricate plotting, acerbic wit, and psychological depth to deliver a masterfully constructed mystery. The story unfolds at Swanswater, the home of wealthy Sir Richard March. Surrounded by his extended family—each with secrets and simmering resentments—Sir Richard has just made a dramatic change to his will. When he is found dead shortly afterward, it's clear that someone took deadly exception to his new intentions. What follows is a classic locked-room-style mystery, full of misdirection, clashing personalities, and a clever interplay between motive and opportunity. Inspector Cockrill, the dryly humorous and sharply intelligent police investigator, arrives to untangle the web of lies, jealousies, and past grievances. As more deaths follow, Cockrill must navigate the emotional minefield of family drama to uncover the truth. Christianna Brand excels at character development, and in this novel, each suspect is vividly drawn with subtle psychological realism. The tension escalates as hidden motivations and shifting alliances come to light, keeping the reader guessing until the very last twist. Suddenly at His Residence is a brilliant example of Brand's skill in crafting puzzles that are both intellectually satisfying and emotionally rich. With its elegant prose, atmospheric setting, and perfectly timed revelations, it remains one of the finest entries in the Inspector Cockrill series—and a high point of mid-20th-century British crime fiction.
