Fundamentally, the show is about the uncertainty that the British people felt as their society changes. Mrs. Boyle laments how it's impossible to find servants because the lower-class don't know their place. Trotter comments that couples frequently find they've married a stranger because their families no longer check on the background of a partner. Christopher Wren is an effeminate young man who contrasts the very masculine Ms. Casewell. The occupants of the hotel put their trust in the police force, but are failed when Trotter turns out to be an imposter and Major Metcalf, the actual policeman, stands by as Mrs. Boyle is killed and doesn't seem to actually investigate anything.
