In the novel Passenger to Frankfurt, Mrs Worrit is the housekeeper of Sir Stafford Nye.
Shortly after his return from Frankfurt, Mrs Worrit told Sir Stafford that men ostensibly from the cleaners "Twiss and Bonywork" had called to collect his suits for cleaning. Not suspicious about anything, Mrs Worrit had allowed them into his room and to take away the suit which he wore coming back from Frankfurt as well as an old blue pin-stripe. Sir Stafford suspected this was just a ruse. This was confirmed when Sir Stafford noticed that the drawers in his room were tidier than they would normally be, and this was not something which Mrs Worrit would do. Clearly someone had gone through his things.
Later, Sir Stafford saw an advertisement asking "Passenger to Frankfurt" to meet at "Hungerford Bridge". Sir Stafford asked Mrs Worrit which Hungerford that would be. Mrs Worrit thought it might be the Hungerford Railway Bridge near Charing Cross, a supposition which turned out to be correct.
