You've heard of Murder on the Orient Express but what about Murder in Dover Castle?
The castle is holding adults-only whodunnit nights in the autumn.
Each is set in the year 1852 on the evening of a grand banquet in the Constable's Tower.
But there is a bloodcurdling twist when a scream is heard from the kitchen.
You have to use your powers of deduction to solve the crime.
The murder mystery session is over three dates, from 7pm to 10pm, between Thursday, October 31 and Saturday, November 2.
The cost is £60 per person and booking is needed as places are limited.
For this, telephone 0370 333 1183 between 8.30am and 7.50pm Mondays to Fridays and 9am to 5pm on Saturdays.
Meanwhile both Dover and Walmer Castles will hold Spooky Castle sessions during the school autumn half term holiday.
This will be between Saturday, October 19, and Sunday, October 27, during the times of 10am to 4pm.
The event, for adults and children, will feature spooky tours and crafts to make horror masks and other creepy creations.
Residents are asked to come in Halloween fancy dress for the chance of a prize for the best costume.
Entry costs at Dover Castle are £20.90 for adults, £12.50 for children aged five to 17, £18.80 with concessions and £54.30 for a family.
At Walmer Castle it is £11.30 for adults, 36.80 for five to 17-year-olds, £10.20 with concessions and £29.40 for a family.
Entry for English Heritage members is free.
Tickets can be bought at the castles on the day.
