Artwork worth a half billion dollars at today's prices was stolen from Boston's Isabella Stewart Gardner Museum in 1990. Twenty years later, the paintings and drawings are still missing. Who robbed the Gardner? Where is the art?

Marcie Sullivan thinks she may know. She suspects that Colby Reech, the famous painter she is taking care of, was the mastermind of the robbery. She also thinks her demented patient may have killed her brother. Has Reech been offering her clues about where he's hidden the stolen works, or is that just his dementia talking? If the nurse can find what has been lost for so long, does she want the art or does she want the $5,000,000 reward? Or, does she just want revenge for her brother's murder?

A dying investigator and an alcoholic mobster also are looking for the loot. Marcie is getting desperate, but is she desperate enough to join forces with two men she doesn't trust?
