A/N: The title of this story is from a line from the poem "To a Mouse" by Scottish poet Robert Burns: "The best laid plans of mice and men gang aft agley," usually translated "... go oft awry" or "... often go awry."

Gang aft agley

Minerva McGonagall, her back pressed against the cold stone wall and her head tilted just enough so that she could better hear the muffled conversation around the corner, was usually the last person anyone would expect to be in her current position, but this, by all means, appeared to be no normal situation. It wasn't everyday that Severus Snape and Rolanda Hooch had a hushed conversation in a shadowy corner of an abandoned corridor, and Minerva was determined to discover what this was all about.

"Do you think it will work?" Rolanda asked, her voice slightly unsteady with effort to control her obvious excitement.

"Oh, I have no doubt," Severus replied.

"Well, it's about time, anyway. Those two have skirted around each other for years."

"Don't you fear the potential... repercussions?"

"I'm not afraid of the Headmaster," she replied confidently.

"Yes, but I have a feeling he isn't the one we should be concerned about."

"Minerva..." she spoke, her bravery noticeably dwindling.

Minerva's eyes widened as she slowly began to piece together the meaning of their conversation. She strained her hears, anxious to hear what they planned to do. She was torn between staying still and showing herself to break up whatever devious scheme they were plotting against her.

"It's for her own good..." Rolanda went on, sounding as if trying to convince herself more than anything. When Severus failed to respond, she knew the outcome: "We're dead."

"She would try to stop us if she knew," Severus said, a smirk evident in his tone.

"Yes, but she can't now, can she?" Rolanda replied with renewed excitement and defiance rising in her voice. "I wonder how she will react when she finds out that it's too late to stop us... that the Headmaster has already drank his tea... that we laced with love potion."
