As Phryne and associates follow up on a business card clue left by Foyle in Bert and Cec's taxi, they enter a world of Ancient Egyptian-inspired mysticism and murder, where Foyle remains at large and dangerous. Jack is ambushed and knocked out from behind by Foyle; he awakens bound and gagged in an underground tomb leading him to thrash around wildly in a panic trying to escape. Meanwhile, Phryne continues to follow the trail of clues and to investigate Foyle. She does it on her own and is trying to track him down, but he seems to always be one step ahead of her. She chases after him after seeing him but ends up meeting an array of booby traps set up by him on the way and he gets away. Phryne is battling booby traps and dodging hidden arrows from all around her and still has no idea Jack is tied up. How will the two ever stop Foyle when he is so clever?
