JK Rowling's incognito detective novel The Cuckoo's Calling has flown to the top of the Irish charts and it's had a knock-on effect on her debut non-Harry Potter novel, A Casual Vacancy.
The author published The Cuckoo's Calling under the pseudonym Robert Galbraith three months ago and it notched up respectable sales for an unknown writer.
However, following a literary sensation after a leak revealed the true identity of the author, the crime novel experienced a huge increase in sales internationally. In the UK there was a 41,000% increase in sales and publishers Little, Brown say that "re-orders for the book are being taken every day" in Ireland.
The Cuckoo's Calling, which follows war veteran-turned-private- investigator Cormoran Strike, had a number of positive reviews when first published.
Rowling's "outing" has also seen her debut non-boy wizard novel, A Casual Vacancy, re-enter the Irish top sellers list. Rowling says she will continue to publish Cormoran Strike novels under the Robert Galbraith pseudonym.
