Do squirrels swim?

There was movement in the water, on the opposite bank of the River Teme.

A fish? No, we could now see it swimming on the surface. A snake—it was long and thin. And coming towards us.

No: Jane pointed out the furry tail. A rat, then? A very small beaver? (I kept that thought to myself.) A squirrel? Do squirrels swim?

Yes, they do.
