Fans of scary stories and classic horror staying in central London hotels may be interested in an evening with author Jonathan Rigby and Mark Gatiss.
Mr Gatiss, the League of Gentlemen alum and Sherlock creator, will talk with Mr Rigby, whose Studies in Terror book is published this week.
The pair will share their mutual love of gory cinema in front of a live audience at the Barbican.
After the talk, the pair will screen one of the all-time great cult European horrors, Daughters of Darkness.
"[Daughters of Darkness is a] stylish adult vampire movie which ends on a note of divine retribution… the moral is, never take-on a vampire with a car, if all you've got is a bicycle!" commented esteemed reviewer Roger Ebert.
Tickets for the event cost £12.50, while Barbican members can get in for £9.50 and concessions are available for £10.50.
Other Halloween events taking place in the capital include a spooky boat trip through Islington Tunnel courtesy of the London Canal Museum.
In addition to the ride, visitors can enjoy the storytelling and scary decorations on the boats.
Furthermore, people can also stop by the ZSL London Zoo and visit the new bat cave as well as take part in Halloween activities and animal demonstrations.
"Visitors will be able to investigate the dark and eerie habitat of the nine male bats and seven females, when ZSL London Zoo's newest exhibit opens on Saturday 22 October," boasts the zoo.
Other animals for the event include the venue's resident vulture, a skunk and a burrowing owl.
