Avenue to Heaven — Julia Donner

When a coffin arrives on Annie Corday's doorstep she knows who sent it -- her former husband, one of Chicago's most vicious crime lords. Desperate, she decides on a radical solution. If a man can advertise for a wife, why can't she arrange for a bodyguard and temporary husband? Jake Williams isn't looking for a wife when he comes to Chicago to buy cattle but ends up roped into a loco marriage contract. And worse, he can't stop his headlong fall into love with a woman who will eventually leave.
