White Knight/Black Swan is a crime thriller by David Gemmell, first published under the pseudonym Ross Harding in 1993. The novel follows the exploits of Jardine, a bouncer and gang enforcer in working class London in the 1980's. Major themes in the novel are murder, betrayal and redemption.
White Knight/Black Swan was Gemmell's only non-fantasy novel to be published during his lifetime (another crime thriller, Rhyming Rings, was published posthumously).
Long out of print and highly sought-after by readers due to a limited number of copies, the novel is set to be republished by Orion on 24 August 2017.
