A NORTH Berwick author has made the most of lockdown by writing and releasing two books in one year. Emma Salisbury set herself the challenge of writing two more books in her DS Kevin Coupland series this year, rather than her usual one. Sticks and Stones was published in April and she has now released the seventh book in the series, When Darkness Falls. In the novel, set in Salford, where Emma was born, the body of a teenage girl is found two days after she is reported missing. A discussion with the pathologist reveals that another girl was found in similar circumstances.
