Right and wrong are still satisfactory alternatives""--the only ones for adamantly honorable detective Crocker. Thus when he sees the Home Secretary frequenting the same teen-aged prostitute as the trade unionist he has under surveillance, he reports it in other High Places and refuses to be silenced with a promotion. This is a story of morality rather than crime, of Crocker's need to conserve old values even if it costs him a great deal, including his closest friend. It is Crocker, only too aware of those dim margins of middle age, change, corruption all closing in, who gives the book its character. Working with fine details and intersecting situations, Ferris achieves a sense of actuality and consequence. Estimable.
