Winter Rogue by Emma V. Leech

A wicked libertine whose luck has run out…
Justin Langley, the Earl of Rutherford, has followed in his dreadful father’s footsteps. Charming, witty and fashionable he might have been, but last earl put a period to his life when Justin was a boy, with nothing but unpaid debts, a notorious reputation and a good many broken hearts to show for his time on earth. At the age of four and thirty, his son has emulated his sire in every way. The only thing left to do, is blow his brains out and follow the path to its inevitable conclusion.

Recuperating from a bullet wound inflicted by a cuckolded husband, his last scandal finally has the ton turn their backs on him, and no amount of charm will win them back this time.
