Ang was in their bedroom, ostensibly putting away laundry, but actually making an entry in her diary, "Be right there. I'll just finish the laundry."
She scribbled a few more cryptic symbols, and added a couple of lines of coded text, then closed the book, and wrapped it again in the jumper she kept it folded in, then tucked it back in the bottom of the drawer it was hidden in. Then she calmly went back to putting away folded laundry, the task she was originally supposed to have been doing.
