Likely, there's a murder at the center of "Deadly Triplets" but who's been killed and who did the killing keeps changing so that you're left you feeling as though the world is full of assassins or maybe you're simply going mad. Far from frustrating, Kennedy's psychological portrait of a divorced playwright living large in London who's search for her could-be-dead mother are interrupted by pernicious intrigues between two lookalike brother-actors is nothing short of fascinating. An addendum compiling Kennedy's sketches of famous theater artists (Edward Albee, Laurence Olivier, Michael Weller) is also enjoyable if decidedly less ominous.
