I'm reading about the theft of the Irish crown jewels.

the wikipedia article says "it was never solved"

but it also says

• The jewels were transferred to a new safe
• Sir Arthur Vicars, the Ulster King of Arms, had it placed in his library.
• two keys to the safe containing the regalia were both in the custody of Vicars.
• Vicars was known to get drunk on overnight duty and he once awoke to find the jewels around his neck.

now, I'm no jewel detective:

but

has anyone looked into this Vicars fella
