Preparing for a terrorization

Satisfied she's gone, you put on a pair of gloves and get out some of the stuff you bought earlier, putting it on the coffee table in the living room. Following the plan you have concocted and fine tuned since the idea first occurred to you that afternoon, you take one of the 'Chanel' branded perfume bottles. Laying it on a bed of tissue, you break it, taking care not to damage the logo. That done, you place the tissue wrapped results in a small box, and place a small toy train locomotive among the shards. Finally, using block capital letters, you write a note in red felt pen, then trim the paper so it fits perfectly inside the box atop the tissue.

You smile coldly as you look down at the terse message, imagining the fear and likely panic that it and the contents of the box will cause. 'WE KNOW WHAT YOU DID' will be the first thing Chanel sees when she opens the box, followed by the toy train and the shattered bottle bearing her name. If you correctly read her fear of the previous night correctly, this should terrorise her. You put a lid on the box, then tied it shut with a red ribbon before laying down to rest and wait until well after midnight.
