When an industrial heist ends in murder, a daring British lord must search for a dangerous group of criminals in this classic crime thriller. The Boothroyds Limited textile company owes its financial success to a secret chemical formula for synthetic silk. It also allows Lord Charles Dutley, son and heir to the founder, to live a pampered life and travel the world. But after nine months of big game hunting abroad, he returns home to England to terrible news. Thieves struck Boothroyds while he was away, stealing the secret formula and killing the only remaining man who knew it. With the Yorkshire police and Scotland Yard baffled, and his company and future now in jeopardy, Dutley must begin his own investigation. He enlists help from Grace Parkinson, the intrepid daughter of Boothroyds' managing director, and together they navigate a treacherous world of power players willing to do more than steal to win. Originally published in 1930.
