The Epiplectic Bicycle by Edward Gorey

This quirky story tells the adventures of Embley and Yewbert, two children who are hitting each other with croquet mallets when they encounter a mysterious bicycle, with a force of its own. I appreciated the way the creepy bits of the tale (for example, the bicycle seems to move on its own, and time passes differently in different parts of the tale) were normalized. Strange but delightful.
