Jack-in-the-Box

''Jack-in-the-Box'' begins with an archaeological excavation at an ancient Roman camp, which unearths a stolen Viking hoard of gold. According to local lore, a curse promises death to anyone who disturbs the treasure. Soon after, the gold vanishes, and a series of bizarre events unfold. As a primary representative of the "Humdrum" school of Golden Age detection, Connington relies heavily on ingenious scientific principles to construct and solve his mysteries.
