One of the great things about writing mysteries is that there is so much material in real life to choose from. Take for instance the mysterious disappearance of Natalee Holloway. An Alabama judge declared her legally dead in January of this year (2012). But her body has never been found. The mystery of her death and of her killer goes on. A good topic for a murder mystery, isn't it!
The question is, do fictional murder mysteries (most of them) have some basis in real life? My guess is, they do. We write best about things that we know about. Besides, truth truly is stranger than fiction. After all we have yet another Aruba Mystery, don't we! Robyn Gardner. Though I shouldn't say she was murdered. She's missing. The same as Natalee Holloway.
A good name for a murder mystery might be "The Aruba Murders." Sound good? You heard it here first. Try it out. It might sell.
