An apostle spoon is discovered after Johnny is visited by a wraith of Father Higgins. The utensil, whose handle features Saint Thomas, is later a clue to the priest's whereabouts (The Secret of the Underground Room, 29).
Apostle spoons are usually silver or pewter with an image of an apostle or other Christian religious figure as the termination of the handle, each bearing his distinctive emblem. Apostle spoons were particularly popular in Pre-Reformation times when belief in the services of a patron saint was still strong. They symbolize the Last Supper of Christ in the company of the Apostles. Shakespeare refers to them in Henry VIII and they’re mentioned by other dramatists of the period. Saint Thomas is distinguishable from the others by the spear that he holds.
