Gideon the Ninth (The Locked Tomb, #1)

by Tamsyn Muir

“My conclusion: if the murders are linked and if some adept, rather than a revenant force or the facility itself, is behind the construct you saw—then it is one of us,” said Harrow. “We’re the only living beings in Canaan House. That means the suspect list is the Tridentarii; Sextus; Octakiseron; the Second; or myself. And I haven’t discounted Teacher and the priests. Septimus has something of an alibi—” “Yes, being nearly dead,” said Gideon. Harrowhark said, rather grudgingly: “I’ve downgraded her in some respects. Logically, judging by ability, and mind, and the facility to combine both in service to an end, it’s Palamedes Sextus and his cavalier.” She shook her head as Gideon opened her mouth to protest. “No, I realise neither has, as you might put it, a fucking motive. A logical conclusion is worth very little if I don’t have all the facts. Then there’s Teacher—and the Lyctor laboratories—and the rules. Why those theorems? What powers them? Why was the Fourth cavalier killed, but you left alive?”
