I think Lisa knew that the mortgage was paid off, but didn’t query much about where the money came from, or how their holidays etc had been funded.
I suppose the dastardly Becky pretended she had an inheritance, or a win on the premium bonds or lottery.
I still want to know, who exactly was Betsy’s birth mother, was it Lisa or Becky?
Property might be good value in Weather field. Two police officers, one a sergeant could probably pay off a mortgage. Obviously depends on the house and price. Betsy is 16 or 17 I think so they might have bought it 20 years ago.
I think I'm overthinking this.
