This is one of those dramas where simply to mention the sort of things that it brings to mind is to give away the plot.: the plays of Dario Fo and Tom Stoppard, or, on television, 'The Singing Detective'. One one hand, it's nicely executed, even if there'a certain element of cliché in this Edinburgh-set detective story, the necessity of whose introduction only eventually becomes apparent. But ultimately, there's none of the deep psychological underpinnings that characterised 'The Singing Detective', and the result is a story that whose whole is a gimmick, essentially less than the sum of its parts. One compensation for those of us who love Edinburgh is the fine use made of the city throughout the film.
