During the first act Mr.Beard joined the party and toward the end of the performance, Mr.Whitmore arrived.
"On leaving the opera house, Mr.Whitmore separated from the others.
Collins, Mrs.Collins, Ward and Miss Burden returned to Delmore Park in the Collins machine.

Beard accompanied them and spent the night with Mr.
Ward.

Mr.Whitmore slept in Mr.Beard's home that night.

Now what becomes of your theory that Mr.Whitmore was shot by one of my clients?
Miss Burden was with them before, during, and after the performance." Here was another alibi, more potent than the others.

For it was evident that if Whitmore was shot after the performance at the opera house, none of the four suspects could be adjudged guilty of the crime.
