Who Killed the Very Reverend Toby Spoon?

You selected William Fitzwilliam

A likely suspect, if the intended victim was indeed Lord Snuffington, or even if it were Reverend Spoon. If he didn't know that the change to the will had been made, he might want to kill Snuffington to secure his inheritance. And if he did know, he might want to kill Spoon out of spite. Still, did you find any clue that might incriminate William Fitzwilliam? No. One of the suspects is lying. Who is it?
