And the intrigue! . . . [A Gentleman in Moscow] is laced with sparkling threads (they will tie up) and tokens (they will matter): special keys, secret compartments, gold coins, vials of coveted liquid, old-fashioned pistols, duels and scars, hidden assignations (discreet and smoky), stolen passports, a ruby necklace, mysterious letters on elegant hotel stationery . . . a luscious stage set, backdrop for a downright Casablanca-like drama. The San Francisco Chronicle.
