his life. âWhere are we headed?â Scarlet asked as Mr Doyle angled the Lionâs Mane towards the coast. âTo a small town called Wick. Professor Stein was one of the experts to discover the Broken Sun. Originally from the United States, he now resides in a castle known as Castle Wick.â âCastle Wick in the town of Wick,â Jack said. Mr Doyle winked at them. âLetâs hope heâs not wick-ed.â Jack and Scarlet groaned. âIt was a ruin,â Mr Doyle went on, âuntil it was restored several years ago. Hopefully it will still have the same fortifications.â They travelled on in silence. Mr Doyle followed the shoreline until they were almost at the most north-eastern point of the mainland. Beyond here Jack could see only the specks of land that made up the Orkney Islands. Mr Doyle gave a grunt of satisfaction and brought the airship down in a meadow. Castle Wick was a large square structure with battlements, perched perilously close to a cliff face overlooking the sea. To Jackâs eyes the building looked authentic; whoever had done the restoration had done a fine job of it. Scarlet pointed to one of the windows. âI just saw a curtain move.â âThey probably donât get many visitors in this part of the country,â Mr Doyle said. âI hope the professor is gracious.â The entrance was an oak door set into the stonework. It swung open as they approached and a gaunt man, reminiscent of a praying mantis, appeared. âState your business!â he snapped, with the trace of an American accent. âMy time is precious!â âAre you Professor Stein?â âI am.â âWe believe you may be in great danger.â âDanger? What kind of danger?â âA piece of the Broken Sun has been stolen from the British Museum.â âThatâs garbage! Impossible!â Jack shot Scarlet a look. And we came here to help this man? âIâm afraid it is the case,â Mr Doyle said. The professorâs eyes narrowed. âI see. And you think someone may be coming here to steal my piece of the map? Castle Wick is impregnable. Nothing can breach its defences.â âYet you have been worried,â Mr Doyle said. Stein folded his arms. âWhat gives you that idea?â âYou were cleaning your gun this morning.â The professor blinked. âHow the hellââ âIt is simplicity itself. There is a distinctive mark on your left hand that results from the cleaning of a revolver. In addition, I can smell the oil used on such a weapon.â For the first time, Richard Steinâs confidence was shaken. His eyes searched the open fields behind them. âI am simply being cautious,â he said. âThe Broken Sun is a priceless artefact.â âHave you checked it today?â âThere is no need.â âI suggest you do so.â âThe impudenceââ Stein almost bounced up and down with anger. Somehow he regained control of himself. âWait here!â The door slammed. âWhat a lovely man,â Mr Doyle said. âWe must invite him for Christmas.â âWhat will we do now?â Jack asked. Mr Doyle sighed. âHelping a man who claims to not need assistance is rather problematic. It would seemââ But he did not finish. A shot rang out. âWhat the devil!â There was a cry, and another shot from inside. Mr Doyle pushed against the door; the professor had not bolted it. They rushed through a cloakroom into a foyer decorated with armour and family crests. Up a winding staircase, they found Professor Stein on the floor in the hallway, his face white with terror. He pointed into a room with a shaking hand. âThere!â he cried. âThere!â Jack caught a glimpse of a figure disappearing through the windowâthe black-haired man from the museum. Jack tore to the window, only to see
