Possessed of a brilliant mind and a love for puzzles, Lord Dashiell Matthews is a crucial member of the elite Young Corinthians spy league. Assuming the facade of an addle-brained Adonis, he hunts for a notorious London murderer known as the Rook. When fate causes him to cross paths with Lady Elena Barnes, Dash discovers an enigma that will prove delightfully intoxicating to unravel: a voluptuous beauty as intelligent as she is fearless. Only the lure of a collection of rare books bequeathed to her family by Dash's late father could tempt Elena from her cozy rural life to the crush and vanity of London. But if Elena finds his lordship to be the most impossibly beautiful man she's ever seen, he also seems to be the stupidest.
