Meet Al MacBharrais. He's blessed with an extraordinary white moustache, an appreciation for craft cocktails - and amost unique magical talent. He can cast spells with magically enchanted ink, and he uses gifts to protect our world from rogue minions of various pantheons, such as the Fae.
But he is also cursed, and his apprentices keep dying in peculiar freak accidents. When his latest one turns up dead in suspicious circumstances, Al's investigations will take him through Scotland's magical underworld, and he'll need the help of a mischievous hobgoblin if he's to survive...
