I gather Madam Headmistress wishes to see me when I come back, and I don't know how long that will take. Make free use of the workroom or the top of the tower, and I'll find you when she's done with me? It'll be sometime between maybe half-nine and half-ten, I hope.

Thank you - and I'll thank Linus too - for the work and the copies: I am sure between us we can get them in the right hands.
