How does Miss Rachel act when she see Mathew Cuthburt going to town?

Mrs. Rachel is completely confused by Matthew's actions, and she makes up her mind to immediately visit Green Gables and find out exactly what he's up to.

"I'll just step over to Green Gables after tea and find out from Marilla where he's gone and why," the worthy woman finally concluded. "He doesn't generally go to town this time of year and he never visits; if he'd run out of turnip seed he wouldn't dress up and take the buggy to go for more; he wasn't driving fast enough to be going for a doctor. Yet something must have happened since last night to start him off. I'm clean puzzled, that's what, and I won't know a minute's peace of mind or conscience until I know what has taken Matthew Cuthbert out of Avonlea today."
