Melinda had been buying another so-called protective amulet - Mr. Weasley apparently thought it was a good idea if she kept going back for more, but since she got out of work for an hour or so, she wasn't going to complain.
She had just picked up a rather ugly looking brooch that apparently had protective qualities when she heard an absolutely manic, mad laugh. Turning, she frowned at the blonde in the middle of the street, cackling away. Honestly, didn't she know people were trying to shop?
Bloody hell - did she just pull a wand on the other witch?
Melinda's eyes widened and then she heard the Stupefy a moment before a burst of red light hit her. She had a moment to think 'Bugger, I hope nobody steals my purse' before she went unconscious.
