Frank

Frank waits until he knows that Craig is working and Kate is at her house alone...

Gathering a £1000 in notes out of his bank, in order to use it to talk Kate into things, he heads over.

He turns up, approaching the door he attempts to knock it only to find it ajar.. he pauses waiting for a min to decide to go in or knock. Deciding to go in he looks around, no sign of her on the bottom floor. Slowly creeping up the stairs he hears her...

He also sees her phone and could go through that?

But is it coming from the bathroom or the bedroom?
