Masterpiece for the Mastermind

This real estate ad is unfortunately rather hard to read, but the tagline is 'masterpiece for the mastermind'. Seems they're trying to corner the local market on masterminds (and art aficionados, as masterminds often have expensive tastes). This is going to be a hard sell though - masterminds tend to want their own private HQ in a hollowed out volcano or refitted Latvian castle, rather than share space with the competition. Or maybe thats the point; the line does say 'mastermind' singular, so perhaps they're hoping to persuade a single supercriminal or evil scientist to take advantage of a readymade citadel. You supply the minions of course, but they supply the missile launch pad, deathray bay, and swimming pool - ready to stock with your own mutant sharks. Saltwater of course; and yes its hard to maintain and pricey, but no expense has been spared. Hell you can afford it - you're a mastermind...
