Suddenly, he clapped his large hand on the housekeeper’s, like a trap, as she stretched it across the table.
– Charles Dickens
Great Expectations, Chapter 26. Pip uses a simile to compare his lawyer and guardian Mr. Jaggers clapping his housekeeper’s hand to the springing of a trap. This suggests the predatory nature of the powerful London lawyer in exploiting people’s weaknesses for the benefit of clients.
