Adrian Mole and the Weapons of Mass Destruction joke in the book is that Adrian does not know whether Mr Carlton-Hayes' partner Leslie is a man or a woman; this is never made clear. Although they are from different backgrounds, he and Adrian share an appreciation of literature, contempt for Michael Flowers, and a similar reservation about expressing their feelings. It is revealed in that Leslie is a man and implied they both left their wives for their relationship. Pauline is Adrian's mother, and plays less of a role in the story than in previous books. Like Adrian, Pauline is inclined to spend using money she hasn't got.
Adrian Mole house down. Adrian ends up working in an antiquarian bookshop. Having lived in relative poverty for much of his life, and for some time in London in actual squalor, he overextends himself financially, lured by the banks' promises of easy credit, and buys a converted loft apartment, at Rat Wharf. He is terrorized by swans, buys a talking fridge, and enjoys his newfound freedom as his children are "off his hands". Glenn is now in the British Army while William is living with his mother and Mole's ex-wife, Jojo, in Nigeria. He gets caught up in a relationship with Marigold
