Jeremy had decided to go to dinner with friends and then onto the Notting Hill carnival when arriving back in England. He told Ann that he was selling everything inside WHF, apart from a few things he was keeping for himself.
The silencer test results were three weeks away & the police had refused to search Jeremy's cottage. Despite the relatives request.
An impatient AE & RB drove to the empty WHF to try an experiment. From outside she tapped a kitchen window. The catch fell into place. Locking the window from outside and making it impossible to use to gain access into WHF from.
The police were contacted.
