In typical Hardy Boys--er, Glen & Tyler fashion, there are secret passages, irascible old men, caves, missing treasure, fine liquor and kilts. Ok, the kilts thing is new -- but believe me, you'll like 'em. Although there isn't much hockey this time around, there is shinty*. There's also some romantic anniversary thing, but really, stay for the shinty.
* For those readers unfamiliar with the ancient sport of shinty, think hockey played on a field, without protective gear and with a solid rugby sensibility. Or a riot with sticks and a score keeper.
