Kensy and Max are back in London for a mere minute before things begin to heat up – quite literally. Is someone still out to get them? Meanwhile, Granny Cordelia has an important assignment that apparently only they can handle, and so the pair are whisked off to Australia.

Kensy and Max must employ all their spy skills – the fate of their parents, and who they’ve been searching for, depends on it.
