Under the incubus' protection

I was prepared to disconnect the call, but Elaine spoke again. “I am sorry. It might upset you, but I am not letting your incubus take the contract from my home.”
“What do you mean? How do you plan on stopping him? He may have taken it already.”
“Being a witch, I am extra cautious with these things. We underestimated your incubus’s power back at Madame Long’s hut. His strength is almost as much as the most destructive and dangerous demons. After witnessing how attached he has become to you, I feared he might steal the contract and manipulate you into wanting to burn it. That’s why I have kept it somewhere safe. It’s inside an enchanted chest he can’t touch,” Elaine replied.
