There Was a Murderer In Our Midst!

On a recent dark and stormy night, a whole pirate ship's crew invaded our clubhouse for a little friendly cheer. As the rum began to flow, it the barrel's tap got plugged up. A quick check revealed a severed head gumming up the works!
​Since the rum still tasted good - even with a good head, the mateys kept the grog flowing as they scratched their heads and the clues to find the guilty party.
​Can you spot the guilty party?-)
