Batman would be nothing without his gadgets. Though you won't find any bat-shaped boomerangs or bat spray shark repellent at Spy Headquarters, they've got the next best things. Bear repellent. Grappling hooks. A hidden wall safe. There's even a portable lie detector so you know when your spouses, kids, or archenemies are telling the truth. We especially love the book selection at Spy Headquarters (though we can't imagine what decent, law-abiding citizen would need to know how to escape from handcuffs, spy on a neighbor, or collect money using shady and sometimes brutal techniques). Blame it on the owner's firm belief that the flow of information should never be restricted, despite the probability that it could be used to commit a crime. Remember: With nanny cams, Tasers, and lock-picking instructions come great responsibility.
