THE VENICE CASEBOOK: ONLINE EDITION

Detective Otis is in Venice, and nobody at dinner is behaving. A waiter is tripped, a goblet is cracked, a bell rope is cut. Forty-eight guests sit at every table, and the seating plan is all Otis needs.

Solve twelve seating-plan cases, then take the twelve culprits to the Masked Ball, where somebody has lifted a rare necklace in front of twenty-four thousand people. Your culprits become signposts in the crowd: first to the right chapter, then the right page, then the one thief.
