The Totally Spies are on the case because it has some high - tech implications, while Martin Mystery is interested because it has a dark and mysterious past.

The Totally Spies' ability to hack into security systems and their combat training comes in handy, while Martin Mystery's ability to decipher ancient inscriptions and deal with the supernatural helps them understand the true nature of the curse.
