Operation Jigsaw is a three-book thriller trilogy by Mark Hayden, published in 2015. The series introduces Conrad Clarke in a more grounded thriller setting before his transition into the magical world of The King’s Watch.
A Piece of Blue Sky, Green for Danger, and In the Red Corner follow Conrad through a series of investigations. While these books lack the fantasy elements of his later series, they establish the resourceful and dry-humored character readers come to know in The King’s Watch.
