Sampson and two mice venture forth to raise funds for a new roof for the church. Between trying to makes a commercial and being put in a London zoo they eventually manage to return home.
Church Mouse (The Church Mice #1)
The first in the series, this book explains how Church mouse Arthur, lonely for the company of other mice, convinces the Vicar to allow other mice to live in the church, where they will perform chores in exchange for cheese. Also resident in the church is Sampson, a reformed orange tabby, who has listened to so many sermons he resolved to treat mice as his brothers.
