And Dangerous to Know [EPUB ebook] 

Spinster Alice Dunbar disappeared shortly after her old and wealthy Aunt Woodworth died. But no one connects the events except Gamadge. Daughter of a comfortably well-off family, Alice’s dreary life consisted of running household errands with the family chauffeur. What motive would she have to run away? She had no money, no vices, and no lover. Or did she? Once Gamadge discovers the true destination of Alice’s frequent drives, he finds himself racing down a winding, dark road that leads straight to a very dead end.
