Anthony Peardew is the keeper of lost things. Forty years ago, he carelessly lost a keepsake from his beloved fiancée, Therese. That very same day, she died unexpectedly. Brokenhearted, Anthony sought consolation in rescuing lost objects --- the things others have dropped, misplaced or accidentally left behind --- and writing stories about them. Now, in the twilight of his life, Anthony worries that he has not fully discharged his duty to reconcile all the lost things with their owners. As the end nears, he bequeaths his secret life's mission to his unsuspecting assistant, Laura, leaving her his house and all its lost treasures, including an irritable ghost.
