After traces of arsenic are found in Sid's blood, policeman Rob brings Charlotte back in for questioning. Is she behind the attack?
Charlotte Hill may have been cleared of her husband Grant's murder and released from prison, but policeman Rob Hollins isn't completely convinced she's an innocent woman.
So after Dr Sid Vere collapses and is taken to hospital in a suspected case of poisoning, Rob and his colleague DCI Joyce Ordega bring Charlotte back in for questioning.
Information has reached them that Charlotte met up socially with Sid twice (as well as her attempt to 'friend' him on social media), so the police want to know if she is somehow connected with Sid's unfortunate poisoning? But, once again, Charlotte denies foul play. So what's going on?
At The Mill, everyone's alarmed about Sid's poisoning and Dr Zara Carmichael is furious with new practice manager Becky Clarke for failing to mention Sid's new patient was convicted murderer Charlotte!
But the question is: Will Sid survive after traces of arsenic are found in his blood...
Meanwhile, midwife Ruhma Carter tries to help a stressed-out student midwife Leia Daniel, whose girlfriend died six months earlier and is now struggling to keep up with her training.
Will the pressure prove all too much for grief-stricken Leia?
