"Things are going well for Detective Sergeant Bruce Robertson. Promotion is in the offing, he's got all the booze and drugs he needs, and his various plots aimed at friends and colleagues seem to be working out. Robertson, compulsive and repulsive by turns, has only two problems. One is a case of racially-motivated murder on his patch. The other is that there's a nasty tapeworm in his gut and it seems intent on having its say... A brutally sustained achievement" * Evening Standard *
