When the Golem is suspected of bringing about the catastrophic destruction of Hammersmith Bridge, Pimm tries to destroy it. This is impossible, as the inscription predicts: "for neither by fire, nor water, nor force, nor anything by man created" can it be destroyed.
Pimm tries to destroy the Golem after suspicions arise that it is responsible for the destruction of Hammersmith Bridge. However, this proves futile because an inscription states that the Golem cannot be destroyed by any means, including fire, water, force, or human creation.
