Conducting his investigation, Jacob discovered that the culprit was in fact Raymond, who was posing as a guard in order to steal the Sceptre of the Queen. His deception involved taking spider venom to induce a death-like state so he could watch the Queen enter the combination to her safe when she assumed a thief was after it, as well as leaving a series of false clues that the palace would be bombed, in order to allow his escape.
