The residual hostility and suspicion between the groups makes things difficult and forces Checquy Rook Myfanwy Thomas to reassign Pawn Felicity Clements from a coveted position on an assault team to serve as Odette's personal bodyguard. Meanwhile, a series of manifestations that could be of Grafter origin threaten the negotiations. Could the negotiations be an intricate double cross or are things not quite what they seem?
