Keeper of the keys
(Book - Large Print)

"For ambitious, troubled architect Ray Jackson, the nightmare begins when his wife disappears. No phone call, no ransom note, no body, reveals whether Leigh is dead or alive. Then a woman shows up demanding answers: Kat, an old friend of Leigh's. Suspected by her and by the police, Ray launches a desperate search of his own. Using a collection of keys to homes he and his mother once lived in, Ray quietly yet boldly enters each house, one by one, hoping to unlock the secrets of his own past."--Page 4 of cover.
