Odds On by Michael Crichton writing as John Lange™

The very first novel by Michael Crichton, the legendary creator of Jurassic Park and ER

Steven Jencks has planned the perfect crime. Working with two skilled associates, he will hit the Reina, a super-luxury hotel off the coast of Spain, and then walk away with the haul of a lifetime. As the ultimate pro, Jencks has even run his plan through a complex computer simulation to account for every possible variable ... 

Except three. 

Their names are Annette, Cynthia, and Jenny. And no computer could ever simulate what these three femmes fatales have up their sleeves.

With a new introduction by Sherri Crichton
