When Detective Dirk Dilly gets a surprise visit from a Sea Dragon in need of his sleuthing skills, at first he dismisses the case. After all, dragons are extremely high risk and they rarely pay well. But soon Dirk is stuck - from his horny head to the tip of his scaly tail - right in the thick of a dramatic new mystery full of unexpected danger.


His trusty friend Holly has made some startling discoveries too, and it's not long before Holly and Dirk are together involved in perhaps their slipperiest mystery yet, involving the strange disappearance of a sister, a dodgy billionaire and some very powerful dragons. Not to mention they will make some unlikely friends along the way in this compelling and plot-driven story full of exciting and unusual twists and turns.
