The Missing Brides — Cindy Holbrook

WHO NEEDS A MARRIAGE OF CONVENIENCE...
For Matthew Severs, Earl of Raleigh, a marriage of convenience--to a bride with the funds he so sorely lacks--is the only sensible course of action. What's become quite inconvenient, however, is the way his prospective wives keep disappearing! Dotty Aunt Clare is behind the mishaps, of course--and his spirited neighbor Penelope Lancer has taken her side in the matter!

...WHEN TRUE LOVE IS SO SWEET?
Penn can't help feeling that the elderly matchmaker is only trying to help--after all, she's promised to find Matthew true love! And although Penn believes her old tendre for Matthew is long dead, the fact that she is apparently not considered an eligible candidate stings. Still, the polite thing to do is join the search for the missing brides--and hope that she doesn't lose her heart to Matthew once more.
