The Sunday Philosophy Club by Alexander McCall Smith

In this book by Alexander McCall Smith, Isabel Dalhousie is intent in chasing her tail around until she satisfies her curiosity about an "accident" she witnessed. Add meanderings about Philosophy, intrigue and dashes of suspense to this central plot and you get "The Sunday Philosophy Club." Overall, I found it about as interesting as a lecture on Platonic epistemology on a searing summer afternoon.
