Carol, the heroine of "Cock", is extremely dissatisfied with her married life. Realisation that her husband Dan is not the man for her has come too late and insult follows injury as Dan's drinking problem gives way to an obsessive fervour for Alcoholics Anonymous. One evening while Dan is out, Carol discovers something entirely unexpected about herself that leads her into rather twisted and distinctly uncharted waters. On the flip side, there is Bull. John Bull is a man's man. A rugby player, a drinker. He's also about to wake up to something of an anatomical surprise, a surprise that his doctor seems to be much more interested in than is entirely proper.
