My guest this week describes his writing as a constant state of striving – to achieve the same visceral punch of great music. His books come to him that way too – protagonist, thread and plot in one hit. In fact I’ve actually seen this thunderbolt descend; I was with him on a course one day when he told me he’d just overheard a conversation that gave him an entire plot and its characters in an instant. After that comes the hard work, of course, and music helps him return to that state of fever. The novel he is talking about this week is the first in a crime series, set in the final years of Moorish rule in Spain, and its soundtrack is full of sweat, guitars, lutes and bass. He is David Penny and he’s on the Red Blog with his Undercover Soundtrack.
