Faking It with the Mafia Boss

I witnessed a murder, now the killer wants me dead before I can testify. Mafioso Nick Falco offers me his protection if I do something for him in exchange. --Pretend to be his fiancée while I produce a priceless painting to solidify his power. Soon, I fall in love and into his bed, only to discover, he's the very enemy I've been running from.
