A Chase in Time — Sally Nicholls

The old gilt-edged mirror has hung in Alex's aunt's house for as long as he can remember. Alex hardly notices it, until the day he and his sister are pulled through the mirror, back into 1912. It's the same house, but a very different place to live, and the people they meet need their help. Soon they are caught up in an action-packed adventure, solving a crime, rescuing priceless jewels, and eating more cake than they have ever eaten before.The first in an exciting time-slip series for 9+ readers from Costa-shortlisted author, Sally Nicholls.
