The world of running is completely alien to Libby Sarjeant and her friend Fran Wolfe, but when Libby's son Adam and Fran's stepdaughter Sophie join the Nethergate Harriers, they have to take an interest.

It's not long before a body is found - and Libby and Fran are caught up in another investigation... The seventeenth instalment in the hugely popular Libby Sarjeant murder mystery series.
