THE ARCHITECT West Crosse is a stunningly brilliant, strikingly handsome architect with a love of ideal beauty and a commitment to achieving it at any cost.  But the rich, powerful families who secretly engage him to design their homes don't know his dark side:  Crosse can't stop at designing their dwellings.  He needs to make their lives more perfect, too, even if it means a gut rehab of the family, even if the final design takes years to achieve--murdering an abusive spouse, a toxic lover, a predatory business partner or an unwanted child.  As Crosse is about to embark on the master work or his creative life, the FBI puts Frank Clevenger on the case, and the ultimate cat and mouse game begins.
