Boy, Bear series

A young boy wanders into an abandoned theater and embarks on a time-traveling adventure to the time of William Shakespeare and the world famous Globe Theatre.

When a boy being chased through present-day London seeks refuge in the National Gallery, a dog escapes from the painting of one Dutch master and together they leap into the painting of another, where their adventures in seventeenth-century Delft are a prelude to returning to London and continuing the chase.
