Give Me Murder Or Give Me Death

The milk boy, oh the milk boy, he was the last person to see poor Julia alive, but at what time?!  A truly intriguing mystery, does the husband's alibi check out, if he didn't kill her who did?  Was William Wallace (yeah that's his name) a chess playing master planner, or a patsy for someone whose motive for murder is unclear?  Also Lena and Alex accidentally reveal their stance on Donald Trump, whoops!!!
