What are the motifs in Master Georgie by Beryl Bainbridge?

What is true in this novel? There are myriad numbers of cover-ups, lies and secrets. The list goes on and on. It begins even before the death of Mr. Hardy, with the Punch and Judy show in the park. Myrtle comments that she has never seen the Punch and Judy man, and because a horse rears up and disrupts his van, she comes spilling out on the ground, cursing, his disguise given away.
