The Silkworm, JK Rowling's second book as thriller writer Robert Galbraith, is to be released in June.
The follow-up to Rowling's Galbraith debut The Cuckoo's Calling, The Silkworm follows private detective Cormoran Strike's search for missing author Owen Quine.
As Strike investigates, he discovers that Quine has completed "a manuscript featuring poisonous pen-portraits of almost everyone he knows".
Billed as "a compulsively readable crime novel with twists at every turn", The Silkworm will be available from June 19 through Little, Brown.
