Questions - caution, spoilers
Several questions related to the killer that Henry has on standby.
1) If the restaurant was staged with staff and patrons, then that means they knew who the hired killer was who came in. Why wouldn't they have made arrangements to protect Celia or to tell the killer that his 'contract' was cancelled. Why would they risk the killer calling Henry to get the go ahead.
2) In the bathroom at the restaurant the killer leaves a wet handprint on Henry's shoulder. Why?
3) If the staff was staged, what was the scoop with the waitress who spilled something and was replaced?
4) If Henry knew that he was going to have Celia killed (to cover up his own guilty act), why bother with all the questions about what happened (he knew he was guilty) and why didn't he tell the killer to just wait until later and do it then (ie, why did he have to give the go ahead)?
