Duels, magic, and plenty of ghosts await in The Mystery at Dunvegan Castle, the third book of T. L. Huchu's USA Today bestselling Edinburgh Nights series.

Everyone's favorite fifteen-year-old ghosttalker, Ropa, arrives at the worldwide Society of Skeptical Enquirers' biennial conference just in time to be tied into a mystery--a locked room mystery, if an entire creepy haunted castle on lockdown counts. One of the magical attendees has stolen a valuable magical scroll.

Caught between Qozmos, the high wizard of Ethiopian magic; the larger-than-life Lord Sashvindu Samarasinghe; England's Sorcerer Royal; and Scotland's own Hamish Manas MacLeod, it's up to Ropa (and Jomo and Priya) to sort through the dangerous secret politics and alliances to figure out what really happened. But she has a special tool--the many ghosts tied to the ancient, powerful castle.
