The title of Nick Payne's latest play (gosh he's prolific) gives a hint of its themes primarily the hidden self. Incognito is an exploration of the sense of self, whether through our own perceptions, relationships or straightforward biology and whether it is truthful.
There are three stories interwoven and presented like overlapping jigsaw pieces, boundaries blurring as the four cast members stride in and out of scenes with only differing accents to distinguish the multiple characters they play.
Two of the stories are set in the fifties. In one After conducting his autopsy, Thomas Harvey steals Einstein's brain to use for research. In the other Henry's life is changed fundamentally after brain surgery leaves him with only a short term memory.
The third, set in the present, follows a clinical neuro-psychologist Martha who is struggling to cope with her patients and with her own radically changing life choices.
Each of the central characters is in some way hidden from their self and it is interesting how they cope with that. Harvey is obsessed with his research to the point where it takes over his life to the exclusion of most others. Henry's life has become frozen at the time in which he was about to go on honeymoon and he can't remember anything outside that for longer than a few minutes.
