Perry Mason has cause to ponder the old adage “Like Father, like son” in this explosive drama of murder among California’s upper crust... featuring a small boy ho just loves guns — preferably those that go Bang!

The curtain rises on Mervin Selkirk’s scandalous divorce. Then, with the battle for custody of seven-year-old Robert still pending, Selkirk’s fiancée, Norda Allison, learns of some unfortunate qualities in her intended. Exit romance; enter letters — crude, threatening ones addressed to Norda.

That’s when Selkirk’s ex-wife and her second husband come on stage, his powerful father lurks behind scenes, and Perry Mason makes his entrance as star in a daring — and deadly — role.
