She Faded Into Air (Timeless Wisdom Collection Book 3922)

This novel is a classic mystery written by Ethel Lina White, one of the best known crime writers in Britain and the USA during the 1930s and '40s. Her novels today keep delighting the lovers of the gendre with interesting plots which conquered the likes of Alfred Hitchcock, whose film The Lady Vanishes (1938), was based on her novel The Wheel Spins.

In this novel, a millionaire family is intimidated by first abduction and death, and when their daughter is taken, at the same place, in the mysterious way, they are willing ransom victims. Good mechanics-timing make this an excellent suspense holder.
