Bookworms will rejoice at this post because it features a well-known and long-established (est: 1918) local book sellers called Swindon Books. The store exterior features extensively throughout the film as the shop owned by Wu's Japanese publisher. Here's a selection of shots from various scenes.
There's also a quick glimpse at the building next door as the binmen come around to pick up the (rather gross) garbage.
And a quick view from one of the upper floors of Anson House (although the store only occupies the first two floors) down onto Lock Road.
