"Fans of the series will race through this hefty page-turner to see where Matthew's latest adventure leads him."

- Publishers Weekly

The year is 1703, and Matthew Corbett, professional "problem solver," is missing. Following a hunch, his comrade-in-arms Hudson Greathouse retraces Matthew's steps only to find him first presumed dead, then accused of murdering a young woman and apparently en route to London with a devious Prussian count last encountered on Professor Fell's Pendulum Island.

Little does Greathouse know, but Matthew is locked up in the infamous Newgate prison and he has drawn the interest of a mysterious mask-wearing vigilante accused of several gruesome murders. Greathouse and the woman Matthew loves, Berry Grigsby, travel across the high seas to England to aid their friend, but it is impossible to know whether they will reach him in time to save his life.

Freedom of the Mask is the sixth installment in bestselling author Robert McCammon's acclaimed series of standalone historical thrillers featuring the exploits of a young hero the USA Network has called "the Early American James Bond." The most surprising and ambitious volume to date, this is a novel filled with unpredictable twists and a note-perfect depiction of early 1700s London. Fans will not want to miss Matthew Corbett's most dangerous adventure yet.
