East Africa, 1918, in the Rufiji Delta Lieutenant Tenton and Captain Mac Griogair of the British Army, welcome Corto on board the Königsberg, a German battle cruiser put out of action by the English. Here, Corto comes across a band of the Leopard-Men - a secretive police force who enforce the native law of Africa - and is dragged by into a tale of secret treasure and old questions of honour and vengeance.
1916, Corto aids the bedouin El Oxford rescue the young prince Saoud from a prison in the middle of the desert in Yemen, where he is held captive by his uncle Abdul and the Turkish garrison. They are assisted by Cuis, a young Danikil warrior from the Beni Amer tribe. Although Cuis's ways begin to grate on Corto's nerves his value is greatly appreciated when it comes to blows!
"I see great danger coming… the slave shall return." This is the chilling prediction of Lochrú the Druid to the High King and his courtiers. But if he does return, will the powers of Darkness be able to prevent his mission? Or can he overcome the druids and the old order? This the second part of the epic tale of Patrick, a tale full of action and spine-tingling tension.
