chunk: In 1974, 11-year-olds Wendy Richards, Jude Cunningham, Kelly Lynch, and Nick McBride play hide and seek in an abandoned convent. 10-year-old Robin Hammond tries to join them, but they start teasing her by repeating "Kill! Kill! Kill!". Robin is then backed up towards a window from which she falls to her death. Instead of reporting the incident to the police, the children make a pact not to tell anyone what happened and keep the incident a secret, but after they leave, a shadow falls across Robin's body. Later a known rapist, Leonard Merch is mistakenly blamed for Robin's death and is arrested.
