My ds7 got quite a few David Walliams books given to him and we were working our way through them. Every story seems to involve an absent mother normally through death , Ratburger , Demon Dentist, Billionaire Boy all the main characters mums have died. Bad Dad and Boy In the Dress both mums just left their sons. Awful Auntie the parents were murdered. Yes they are well written I don't dispute that and death is a sad fact of life but does he really need to have death in every story ? anyone else noticed this ?
