July - S1.E7

The double key code still stumps Cal. He travels to a secluded convent to ask his great-aunt Millicent what she knows about the mystery. Can Cal get a woman who hasn't spoken in 13 years to reveal her secrets? Cal looks through Millicent's belongings and discovers letters from Piers Ormond, his great-great-grandfather. The letters reveal what Cal suspected: the two missing lines of the Riddle are the key to the Singularity. Cal chases down the Ormond family solicitor, Sheldrake Rathbone, in a bid to get Piers Ormond's will. But not all legal eagles are honest and upstanding. Cal's desperation for answers may be his undoing. Is this the end for the 'psycho kid'? 153 days to go.
