Judi Rifkin is one of the world's most successful collectors of the weird and unnatural. In a London underworld filled with criminals with very special talents, Judi is a force to be reckoned with. And Gideon Sable - thief, rogue and chancer - owes her a very large favour. Judi makes him an offer he can't refuse: steal her the legendary Masque of Ra, kept safe in a Las Vegas casino, and she'll wipe the slate clean. This isn't Gideon's first heist by a long shot. But with old grudges threatening to cloud his judgment, an unpredictable crew who don't entirely trust each other and a formidable supernatural security team guarding his target, this job might be a gamble too far . . .
