I found this worth watching even though it makes no sense -
1) Henry was poisoned BEFORE he confessed making the whole charade pointless.
2) Vick sent Henry to interview Bill whilst suspecting that Henry was guilty. This would have given Henry every incentive to kill Bill and pin it on him and so it makes no sense.
3) The fact that Henry had a hitman ready to kill Celia makes no sense given what he had already done to protect her and means that his most logical move would be to kill Bill and claim that he had confessed (see 2)
