Can anyone please explain the ending of the reckoning on stv to me?

I don't fully understand the ending as I am not sure if she killed the lawyer or not, can anyone please explain. Many thanksCan anyone please explain the ending of the reckoning on stv to me?
I found it a bit difficult - Thank God for Sky. The secret was in the conversation in the Taxi Ride at the end. Sally had obviously done 5 years (10 served 5) for conspiracy to Murder, and was greeted by her now very healthy %26amp; daughter Amanda . During this cab ride Sally asked Amanda - Did you visit Reith in Prison?? - REPLY yes, he's the reason I'm here now, it鈥檚 the least he deserves! We, like you were puzzled by the end, so replay and delve into Google found that Reith was the deranged solicitor (Peter Wright) the actor who's in everything at the moment - Silk etc. So the end was, she DID NOT kill 'Reith' (the Solicitor), Her Partner (Max Beasley) was done for murder (serves 12 - 15 years), she got time for conspiracy, Reith the Solicitor obviously had key thrown away, but he showed compassion by financing The daughters (Amanda) Treatment - Vaughan From LeedsCan anyone please explain the ending of the reckoning on stv to me?
