I've been rereading Deathtrap, the play by Ira Levin. It is an elegant piece, very spare in its style, which helps make the mind-boggling self-referencing plot slide along smoothly.
Somehow it comes across as not trying to dazzle you, but dazzling you anyway.
It's an air of modest charm
in a room that's set to harm.
UPDATE: Photo, bring back memories for me, of 3 members of the original Broadway cast, John Wood, Marian Seldes, Clifford Anderson:
