The Marquess Who Loved Me (Muses of Mayfair #3) by Sara Ramsey
A not-so-merry widow… The widowed marchioness of Folkestone is notorious for her parties, her hair, and her utter disregard for the rules. But Ellie knows her destruction is near. The new marquess is her old lover – the man whose sculpted body and sardonic grin haunt her every time she picks up her paintbrush. If Nick ever claims his inheritance, her heart won’t survive seeing him again. A spy by any other name… Nick hasn’t stepped foot in England since watching Ellie marry his cousin. He has no use for the title, or for the gorgeous, heartless girl who betrayed him. But when his mission ends and his colleagues in England start dying, Nick must return to uncover a traitor – even if it means sharing a house with the woman he failed to forget. A love they can’t escape… Nick hates Ellie’s transformation from sweet debutante to jaded seductress. Ellie despises him for leaving her behind. Still, the sparks between them reignite a passion that neither can control. As the killer closes in, they must decide whether to guard the fragile remnants of their hearts — or find a way to fall in love all over again.
