The broom cupboard was musty and full of cobwebs, though this didn't bother the Weasley boys one bit as they slid inside and went to work. Cursing Filch's broomsticks had been a good idea in theory but the truth was the man had so many broom cupboards and even more brooms.
Footsteps broke through their concentration and they quickly slid from the cupboard and leaned innocently against the wall for it was certainly to late to escape. Had Lee Jordan not been in detention they would have had more warning, but you take what you can get.
Professor Lupin appeared around the corner, smiling as he spotted them.
"Nothing like a nice summer day indoors doing things we shouldn't?" he said. They exchanged a quick glance. Fred opened his mouth to speak.
"You needn't worry" Lupin said lightly, glancing down at his watch. "Filch is in the library dealing with a dung bomb and I've just seen Mrs. Norris in Hagrid's garden chasing gnomes. You should have plenty of time to finish off those brooms. "
"Have a good weekend boys" he said over his shoulder as he continued on his way, and they heard him whistling all the way down the corridor.
