The Sorcerer's Widow — Lawrence Watt-Evans

The great sorcerer Nabal's death offers many opportunities, both for those who knew him and those who did not. For young conmen Ezak and Kel,  it means a chance to loot the sorcerer's estate ... if they can win the confidence of Nabal's widow, Dorna. But Dorna has plans of her own. She means to leave the tiny village for a better life in the city. And all of Nabal's magical artifacts and talismans will pay for that new life -- if she can only get them there intact!
