Perhaps the most enjoyable aspect of the missing gold saga at the Royal Canadian Mint is the speculation—some wild, some informed—as to how $15 million worth of it was stolen. The latest theory: someone melted the gold into an acid solution, rendering it immune to metal detectors in place to prevent the theft of precious metals from the Mint. As to the investigation, well, you’ve heard this before, but the Mounties are still investigating. In other words, no one’s holding his breath. Anyway, given the price of your average Hollywood summer blockbuster, $15 million doesn’t seem that bad for a few weeks of intrigue. This may prove to be the heist to end all heists.
