An operation … on Christmas Eve? The note has left Santa with more questions than answers.
As he looks around the workshop he stares at each Elf, busily making toys and wonders where each of their loyalties lie. Should he call a meeting? Will exposing what he knows help to foil the plan or just make things worse?
As he ponders his next move, another note slides under the door.
On first inspection it looks like gibberish, 1s and 0s, but wait!
It must be binary but what does it say?
Help Santa to decode the binary message.
