At the grand English estate of Chimneys, a harmless prank turns deadly. Gerry Wade's friends plant eight alarm clocks in his bedroom to cure his oversleeping; by morning he is dead, and only seven clocks stand in a neat row on the mantelpiece. The missing clock-and the cryptic phrase "Seven Dials"-are the first signs that the joke concealed something far more sinister. Fearless and sharp-witted Lady Eileen "Bundle" Brent refuses to accept the official explanation. Her search for answers carries her from country-house corridors to a shadowy London night club known as the Seven Dials, where whispers of a secret society and stolen government secrets hint at a dangerous conspiracy. As more deaths follow, Bundle finds herself drawn into a plot that is as daring as it is deadly. Meanwhile, the unassuming but formidable Superintendent Battle watches carefully from the background, quietly assembling the truth while masked figures move under the authority of the mysterious "Number Seven." First published in 1929, The Seven Dials Mystery blends classic country-house intrigue with the brisk pace of a 1920s espionage thriller. It may be enjoyed as a companion to The Secret of Chimneys or as a stand-alone mystery. This edition has been professionally formatted from the original text for a clean, comfortable reading experience and features newly designed period-style illustrations that bring key scenes to life-capturing the atmosphere of late-1920s England and the eerie elegance of the Seven Dials.
