The Chilling Crossbow Killer

SO, WHO IS THE CROSSBOW KILLER?
IT was Aber Tidy's annual Festival day. By far the most popular event in Doolally Valley----exciting, spectacular, colourful, a feast of fun and fancy cakes.
Only this year, it would be remembered for the chilling crossbow murder of bank manager Bertie Brown in Bluebell Woods. Shot in the heart and buried under bracken.
Fear flooded the shocked Valley, as Superintendent Matthews and his officers desperately searched for suspects, eventually focusing on the Aber Tidy archery club, where a number of arrows had mysteriously disappeared.
Two further crossbow murders quickly followed, one in Bluebell Woods, and the other in a lay-by on a main road. No motive could be established.
A university criminology student joined the hunt, along with a renowned psychic, and clues gradually began to appear, and the net closed in.
It seemed everyone in Aber Tidy had a different prime suspect.
So can YOU spot the clues, catch the killer, and collect the £20,000 reward?
Good luck
