A Marquess for Convenience — Bianca Blythe

Lady Madeline Mulbourne, widow of a renowned art critic, has secrets.
Pretty secrets.
Sparkling secrets.
Ever since the wars on the continent ended, she's been determined to return the jewels the French confiscated to their rightful owners...even if it means stealing them herself.

Lord Arthur Carmichael, Marquess of Bancroft and a former spy, is in need of a bride. Who is more suited than the woman he'd once intended to marry? But when jewels disappear at balls Madeline attends, Arthur suspects Madeline might have more than one reason for not wanting to marry him...
