There Was A Little Girl by Ed McBain

Published in 1994, still a good mystery with a twisted plot. Attorney Matthew Hope is unconscious after being shot twice by an unknown assailant. His friends take up a desperate search to find out who wanted him dead. Clues leading from a real estate deal for a small circus to the death of a circus performer three years previously seem to go nowhere and everywhere. Ed McBain keeps you turning the page. I really liked it.
