Monarch of Mulligan's Bay

A priest cannot disclose what is told to him in the confessional, even if he is abandoned by his church and confined to a mental institution for the criminally insane. He can, however, share a riddle with a young maintenance man, Donnie Fuller, who keeps him company during breaks by playing chess and solving his brainteasers. The priest’s final riddle is given to Donnie Fuller in 1965 on the night before the convict’s death.
