Open Sesame: The Secret of the Silent Alarm

Everyone believes Lord Victor Ashworth died on an African safari. That is exactly what he needed them to think. Two years ago, Ashworth began his greatest deception: infiltrating a shadowy, numbered criminal society that operates in plain sight. Now known only as "Roger, " he has gained their trust. But when the organization plots its most audacious heist yet-targeting his own family's estate-Ashworth must walk a razor's edge.
Every move is monitored. Every shadow could hide an enemy. Trust is a liability, and a single misstep means a painful death. His only weapon is a brilliant mind and a secret safe engineered with a final, devastating failsafe. As the society's leader lures him into a final, deadly meeting, Ashworth must utter the words that will spring his trap. But in a world of masks and lies, the most dangerous secret is the one he never saw coming.
