The fiance of a children's author who drugged and suffocated her before throwing her body in a hidden cesspit has been found guilty of murder.
Ian Stewart, 56, had denied murdering Helen Bailey at their home in Royston, Hertfordshire, in order to get his hands on her near-£4m fortune.
He was convicted at St Albans Crown Court following a seven-week trial.
Police say they will look again at the death of Stewart's wife Diane in 2010 following the verdict.
Mrs Stewart died after having an epileptic fit in the garden of the family home in Bassingbourn, Cambridgeshire. An inquest was held but police will now re-examine the case.
Stewart was also found guilty of preventing a lawful burial, fraud and three counts of perverting the course of justice.
