He was hit over the head and pushed down the stairs by a member of his family.
After suspecting all of his nearest and dearest, Ken has still been left in the dark about who wants him dead.
But it has now been revealed to viewers who attacked the pensioner.
And if that wasn’t enough, a flashback video has confirmed that Daniel was definitely the culprit.
The clip showed Ken lying face down at the bottom of the stairs.
Daniel is seen stepping over his father’s body holding the book and looking panicked.
Will his secret finally be exposed?
He and his father have gone on a trip to the other side of Manchester next week, in a series of dramatic episodes scheduled for later than the usual time of 7.30pm.
Will Daniel finally finish the job and kill Ken?
Corrie continues on Monday at 9pm on ITV.
