Ripples (The Blake Harte Mysteries #3)
Robert Innes

But once at the Manor of the Lakes, the rest and relaxation they both crave is quickly brought to an end, when Blake and Harrison witness a man being murdered, by a mysterious hooded figure who appears to have the ability to walk on water.
How is it possible for someone to defy the laws of physics? And Blake’s problems are only just beginning. The visit to the manor finds him coming face to face with figures from his past – and one in particular who could ruin any chance of Blake and Harrison ever being happy together.
The ripple effect is well and truly in play…
