It would probably have worked to get us into the office, but the problem was we needed to remove a painting, then tape a message to the wall in such a way as nobody would be interested in reading it. That would be hard to cover for, even for the Doctor, and I get really nervous when I have to rely on Amie's weird fanfic thing.
It gets into my head, and I don't want anything to do with the Botfly anywhere near my mind - if I can help it.
They can't work through the night due to noise ordinances, so that'll be your opportunity.
We decided to wait until dark…
