And Dangerous to Know [EPUB ebook] 

In this mystery novella by Agatha Christie’s favorite American author, a 1940s antiquarian book dealer searches for a missing Manhattanite. Alice Dunbar was a very proper Upper East Side woman with a very boring life. There is, in fact, absolutely no reason why she should go missing, and yet that’s exactly what she does. One hot summer day, shortly after an elderly aunt’s funeral, Alice Dunbar changes into a new outfit, puts on some make-up, and slips into a subway car, not to be seen again. Where was she going? Amateur detective Henry Gamadge, on the case after the police have failed to locate Alice, tracks down her last trip and uncovers a secret life that’s stranger than fiction . . .
