The Cuckoo's Calling is number 1 on Amazon.
At The Blaze: J.K. Rowling used the name Robert Galbraith to write “The Cuckoo’s Calling,” according to the U.K. Sunday Times.
“I had hoped to keep this secret a little longer because being Robert Galbraith has been such a liberating experience. It has been wonderful to publish without hype or expectation and pure pleasure to get feedback under a different name,” Rowling said, according to The Telegraph.
“In a rare feat, the pseudonymous Galbraith combines a complex and compelling sleuth and an equally well-formed and unlikely assistant with a baffling crime in his stellar debut,” Publishers Weekly raved earlier this year.
“Galbraith” came complete with a fictitious biography: a former Royal Military Police officer who took up private security. “The idea…grew directly out of his own experiences and those of his military friends who returned to the civilian world.”
