The dog ate my homework

I have recently started French classes at canary wharf on Wednesday evenings with a company with the unfortunate name of cactus language school. I have been late, missed class, got lost etc and decided this week to be a real spoc, do my homework, and take all my papers with me. So I turned up (40 minutes late) opened my bag and .... No homework no papers not even a pen....
I DISTINCTLY recall packing them this morning.
And I get home after class and find .... No papers here.
They have vanished. Seriously. I've no idea where they are.
