Tread Softly

A complete cannibalisation of loads of other stories, but it's still quite a watchable little drama based on the BBC radio serial "The Show Must Go On". An actress (Frances Day) walks out on a production days before curtain up and Patricia Dainton is selected to fill her shoes. Next thing we know, folks start dropping like flies (including Day) and John Bentley and Ronald Leigh-Hunt get their investigating caps on. We soon discover that 40 years ago, there was a murder in the same theatre...might it be a ghost? It is as well it is set in a theatre, as there are at least half a dozen, decently performed full-length theatrical or nightclub numbers.
