'My favourite American crime-writer' New York Herald Tribune Ireland, 1749. Dennis McDermott, a witty, charming and daring young man with shades of the Scarlet Pimpernel, lives two lives in eighteenth-century Dublin. Fashionable society idolises him as a handsome, rakish man of their world, never suspecting that he is the mysterious leader of the Irish underground whose nightly missions continue to outwit the British authorities. But Dennis' cover as an Anglophile who has renounced his Gaelic roots is under threat from an ever-more inquisitive policeman, and he also is embroiled in another cat-and-mouse game . . . falling in love.
