Though Tracy's fingerprints are on a vase in the flat but can't see that as a problem for now... If Michelle's keys are still with Tracy, then that might be hard to explain.
Can't understand how the fire service knew that the fire was started by a candle. Surely the candle would have melted completely so where was the evidence?
Sure Tracy will drop herself in it, when she mentioned the candle Carla looked sort of sideways as if she was thinking 'how the hell did she know about that' and I reckon she will work it out.

Fire investigators can tell if a substance like candle wax was used. It is what is called an 'accelerator '. Like other 'accelerators' such as petrol or paraffin
they leave chemical traces which can be identified.
Eddie5; I may be wrong - it has happened once or twice during my lifetime - but i don't think you could class candle wax as an accelerant. A candle can, of course, be used as a means of starting a fire (particularly where arson is concerned) as it gives the arsonist plenty of time to distance him/herself from the scene of crime.
Course she'll get found out. Maybe Kylie was skulking and saw Tracy go in to the flat.
Or Tracy will drop herself in it when she's next in a rage with Carla or Liz.
She won't be sent to prison over it, if the police believe what she tells them - she went in to the flat with the intention of bonking Carla over the head and lit the candle to see what she was doing. She had a change of heart, put the candle down and left. She didn't intend the fire to happen
