Speaking of Burke, Declan Burke is an Irish crime mystery writer who falls under the "not well known" category. His 'Crime always Pays' is both a very fun and very inexpensive read. (Smashwords and Amazon). I have yet to read his second book 'Eight Ball Boogie' which I recently bought, but I am looking forward to it.
Not great as in the same class as the others posted here, but defiantly the best .99 cents I've spent lately.
