When Inspector Tanner is called in to investigate a ruthless murder at Mark’s Priory, the grand ancestral home of the Lebanon family, he quickly discovers that nothing is quite as it seems. The household is controlled by the family physician, the footmen behave more like guests than servants and the secretary Isla is afraid for her life. Why are these two American „toughs” employed as footmen? Why is Lady Lebanon so unwilling to answer any questions? What he does know is that the only obviously innocent person is utterly consumed with terror. Here is Inspector Tanner’s first real clue. As Tanner moves closer to the heart of the mystery he uncovers a shocking and closely guarded secret.
