Then the woman turned off

Then the woman turned off the High Street into the little lanes near the seafront. Chrissie was worried she'd notice us away from the crowds, but Ruth just kept going, and we followed behind her.
Eventually we came into a narrow side-street that had the occasional shop, but was mainly just ordinary houses. We had to walk again in single file, and once when a van came the other way, we had to press ourselves into the houses to let it pass. Before long there was only the woman and us in the entire street, and if she'd glanced back, there was no way she wouldn't have noticed us. But she just kept walking, a dozen or so steps ahead, then went in through a door--into "The Portway Studios."
