Also Robin Cook-- Doctor/author
(Coma, Vector, Toxin...)
actually if you read one of his books, you've read them all. in each one young doctor/medical student stumbles on to evidence of consealed murder...he/she starts to investigate, and some older, respected doctor pooh-poohs efforts, hero continues, nearly gets killed and in the end, solves the case...

I like medical mysteries, but his books are such formula novels, they are no fun any more.
