Jim Darby is back on his travels again! Now that he's got his airship company off the ground (ahem) the British Secret Service want him to do another little job for them.

Just pop down to Malta in one of his airships and pick up a certain decoding device for them. Easy you'd think but this one's been stolen from one of Albion's rivals so Jim and his crew have to be discreet. Too bad there's a sexy woman pyrate docked there, who's an old flame of Jim's and she's still smouldering about how they parted. As well as that annoying little matter of another pyrate having put a price on his head of which Jim is unaware, as he flies into danger.

This book's got it all. Thrills and spills! Excitement and danger! Wiener Schnitzels and cuckoo clocks!
