The Marquess Lends a Hand — Monique Ellis

ONE WAY FOR A LADY TO MAKE A MATCH...
Phoebe Parmenter was in a terrible predicament: she was being blackmailed into marriage by her beloved stepmother's wastrel cousin. Under her father's thumb all her life, Phoebe didn't particularly mourn the old tyrant's death in a supposed riding accident. Unfortunately, Philip Fordyce is prepared to prove the squire's death was no accident. If her stepmother is not to hang for murder, Phoebe will have to wed this man she despises.

But neither he nor Phoebe anticipated the perils that awaited them...or a blossoming romance filled with all the wonder and mystery of true love...
