There's a real pleasure in acquiring useless bits of knowledge, such as learning what Odeon stands for: Oscar Deutsch Entertains Our Nation. The son of a scrap-metal merchant, Deutsch built a string of cinemas across the UK in the 1920s and 1930s, starting with his home town of Birmingham, and bringing a splash of Art Deco glamour to our high streets. Now, as part of alternative film festival Flatpack, the writer David Lodge will be dipping a toe into Birmingham's cultural history, with a series of bus tours around some of these original cinemas, ending at Britain's oldest working picture house, The Electric, for some vintage short films.

The shade was on dresses at Erdem and nails at Vivienne Westwood, and is a low-maintenance but high-fashion way to invigorate girly spring shades with a bit of directional toughness. Try Models Own's shade of purple-grey nail varnish and remember: those in the know will be predator and prey this season. £5, modelsownit.com

We couldn't possibly comment as to how many MPs will buy this on the sly, but with just weeks to go before the general election, the publication of British Politics for Dummies (Wiley, £15.99) couldn't be better timed. Written with clarity and brevity (by this newspaper's money expert Julian Knight), it tells you all you need to know about voting, the parties, what history has taught us, and some useful tips on our rights as UK citizens.
