Having landed a small part in a new West End play, The Habit of Faith, Charles Paris is dismayed to discover that his good fortune has been orchestrated by his bête noire, the now-famous screen actor Justin Grover. But why has Grover become involved in this relatively obscure production – and why has he roped in Charles to star? From the outset the production is fraught with difficulties – and matters become even more complicated when a body is discovered at the foot of the dressing room stairs. Did they fall – or were they pushed? As one of the last people to have seen the victim alive, Charles Paris is drawn into the ensuing investigation.
