Laura. Don't worry, darling, they've traced the call. Where is he calling from?
Let me speak to your wife, Mr Richardson. Mrs Richardson? I want you to listen very carefully and act very quickly. Whatever you do, try not to panic. I want you to go as quickly as you can to the front door, and open it as quietly as you can, and get out! We've traced the call. Anderson is upstairs in your husband's study.
