Death Takes a Partner — Dean Wesley Smith

Mary Jo, one of the most beautiful and deadly assassins in all history, loves drinking vodka and orange juice after a job well done. She planned her next kill perfectly. Every detail thought through. But Mary Jo never planned on meeting Jean, the beautiful woman two houses down the street. Jean also loves drinking vodka and orange juice after a job well done. A twisted story of love, killing, and drinking, not necessarily in that order.
