Mystery story Writers

One of the things that add such a huge Zing to my Life I've discovered is a Well- Written-Mystery-Story I go about with such a glow the whole day, its worth it to read lots of these:-)

A recent addition to my list of Favorite Authors is :

Josephine Tey- Elegant Prose - I can't reveal any more mysteries.
Other favorites :
PD James -
Sue Grafton - the A is for ... - lady With a zingy, irascible detective Kinsey Malhone
Mary Higgins Clark - though Ive mostly given up on her.. too horrifying
Ruth Rendell - Macabre but a scholar
Ngaaio Marsh - I've read only one but it was great
Mary Stewart - Unbeatable for mystery undertinged just slightly with romance
Agatha Christie- where one begins

Male writers:
Dick Francis - a very intelligent mind
Lawrence Sanders - though his Commandment books are good, his madly gay detective Mcnally really holds
Raymond Chandler - Style
Giovanni Guareschi's Don Camillo - tho this isnt detective fiction actually
