As soon as Jeffery was sure that Five had gone this time he moved quickly. Moving the king from the room to the next room. As the king's right-hand man he used the room not too far from the King's room.
It made it easy to switch the king and the physician assistant. Inside the water, he had fed the physician assistant a potion that will make him sleep.
After taking the assistant into the room, he set him on the chair as though he had fallen asleep while watching the king. Then he applied herb on his nose that will help him wake up in a few moments.
Jeffery could hear footsteps, drawing closer so he acted fast and brought out a necklace from his pocket. This was the same one Ericsson had used for years to pretend to be Mason.
If it was before, Jeffery would not have needed to use it as no one knew what the king looked like but after he unveil his face king Sebastian has been walking without his black mask very often.
