In which Arthur Dent finds an odd fishbowl, his new love's name, and has some explaining to do over his copy of The Hitchhiker's Guide to the Galaxy. Meanwhile, Ford Prefect plans to build up a massive telephone bill.

Arthur returns to find his house still standing and his telephone ringing, however, he fails to answer it. He also finds a gift on his bed, a goldfish bowl with the inscription So Long and Thanks for All the Fish inscribed on it. He fills the bowl with water and pops his Babel Fish inside it.

Arthur then bumps into the woman he met in the car. The two talk to each other and Arthur discovers that 'Fenny' is short for 'Fenchurch' (she was conceived there). Fenchurch leaves to catch a train to Islington, which Arthur follows.

While down in Islington, Arthur attempts to find the old cave he lived in while he was stuck on prehistoric Earth, and accidentally annoys a man after he tries to donate money to help the dolphins. He then bumps into Fenchurch, who claims that Arthur has some explaining to do - she has found his copy of The Hitchhiker's Guide to the Galaxy.

Ford however, is still trying to get to Earth. In the process, he makes a phone call to the speaking clock in a hope of bankrupting the Sirius Cybernetics Corporation.
