Geocache Description:

This is a bonus cache following on from the “Whodunnit at the Bryntirion Inn” Labcaches.

Whodunnit at the Bryntirion Inn

As with the labcaches, there is no need to go inside (it’s a crime scene!) nor is there any need to interact with staff. When you successfully complete each of the five labcaches, you are provided with information to help solve the Whodunnit and find this bonus cache.

Recapping from the labcache summary….

This morning a body was found. It was cold and lifeless, with blood on both it and the carpet. Shocked, the local constabulary were called and a detective arrived. They asked you to assist in their investigations outside the inn whilst they were investigating inside.

The owners have made a list of everyone who was at the Inn last night. It is hoped that footage from CCTV cameras will be able to reduce this to a shortlist, or even one individual. The detective was sure the murderer was staying overnight but did ask you to check the outside of the inn for anything that could help the investigation

The ‘CLUES’ gained from the labcaches are used in the logic puzzle to work out which nationality of person performed which job, in which room they spent the previous evening, and in which bedroom they stayed overnight.

The ‘CCTV’ footage from the various surveillance cameras provides further information to help identify the murderer.

The ‘EVIDENCE’ images shown when each labcache is successfully answered may or may not help you.

Logic Puzzle

List of those here the previous evening

Use the numbers in the logic puzzle grid against the nationality, job, bedroom and evening location of the murderer to find the bonus cache at :

N 52° 54.(Evening Location) (Bedroom) 4 W 003° 30.(Nationality) (Job) 4

It is recommended that you print off the three attachments below (Sheet 1, 2 & 3) to record all the evidence as it is uncovered and ultimately to make your deductions and identify the murderer.
