It is easy to let your guard down in certain social situations, but client confidences should never be brought to the party. JK Rowling recently settled a lawsuit against her London law firm, Russells, and others. Russells partner Chris Gossage revealed to his wife’s best friend, Judith Callegari, the secret that the Harry Potter author had also written the then-obscure novel The Cuckoo’s Calling under the pseudonym Robert Galbraith. One night in July, just after midnight, Callegari responded to a Twitter post from a Sunday Times reviewer praising The Cuckoo’s Calling with the surprise news that Rowling was the author. Soon the whole world knew, and The Cuckoo’s Calling jumped from 4,709 to the top of Amazon’s sales chart. “[A]ngry and distressed that her confidences had been betrayed,” Rowling sued Gossage and Callegari. Gossage appeared before the British High Court and apologized to Rowling. Russells, which had previously publically apologized to Rowling, reimbursed her legal costs and made a donation to The Soldier’s Charity. Incidentally, Rowling promised to give all profits from The Cuckoo’s Calling to the charity for three years, which is fitting as the book’s protagonist, Cormoran Strike, is a wounded Afghanistan veteran.
