Eliza bounced on the balls of her feet as she scrolled through the website. There it was. Her magnum opus, the culmination of months of research, under the byline ofโ€ฆ "Brenda Billingsworth"? She let out a whoop of unrestrained amusement. Her fingers tapped a rhythm on her desk. Brenda, whoever *she* was, was in for a treat.

First, a carefully crafted email to the editor, full of effusive praise for the "Billingworth" article, sprinkled with leading questions about her writing process. Then, a trip to the local florist. A dozen red roses were dispatched to the editor, anonymously, with a card quoting a particularly obscure line from her own, *ahem*, Brenda's article.

She imagined the editor's growing confusion, the furrowed brow, the inevitable internal investigation. She felt a giggle bubble up, unstoppable.
