When heart-throb American tennis coach Todd Winters careens off the road in his speeding car one night and plunges in the river, it seems like a tragic accident. But Winters was a young man with many dangerous secrets, and Harry and Kat discover there’s no shortage of people who wanted him out of the picture. Soon they discover clear evidence: the accident was no accident at all. And now Harry and Kat had best be careful too... even in the genteel world of the Mydworth Lawn Tennis Club, a desperate murderer could be ready to kill again.
