After 18 weeks at Number 1, ‘Fifty Shades of Grey’ has been knocked off the top spot on the Irish book charts by Irish author, Marian Keyes.

The latest figures show that Keyes’ new novel ‘The Mystery of Mercy Close’ was the Number 1 best-selling book in Ireland last week across all categories, making the detective novel the first to topple the erotic book.

Best-selling author Keyes has sold over 22 million books worldwide.
