In Book 3, Arthur must do the unthinkable: betray his friends and Holmes or pay the price.



Arthur should be happier than ever. He made it into the esteemed Circle of Light, Professor Sherlock Holmes believes he has tremendous talent, and his friendships are stronger than ever. However, Dinah Grey’s ominous letter and her dangerous hold over his little sister Mary have left Arthur riddled with anxiety and fear. It’s not long before another letter arrives and makes the key to Mary’s salvation clear: Arthur needs to insert himself in Sherlock’s next excursion and report back.



When the annual first-year trip to the Lakes is announced, Arthur suspects that the place known for the renowned poets who called it home is key to her plan. While sticking close to Holmes, Arthur meets John Ruskin, one in a long line of protectors of the Brazen Head, a powerful relic whose wearer can ask any question and have it answered. But there are more eyes on Sherlock and the relic than Grey’s. Arthur will have to walk the thin line between truth and deception in order to save his sister, but it might cost him more than he realizes.
