May, 1924. It's been seven months since young British widow Emma Blackstone arrived in Hollywood to serve as companion to Kitty Flint: her beautiful, silent-movie star sister-in-law. Kitty is generous, kind-hearted . . . and a truly terrible actress. Not that Emma minds; she's too busy making her academic parents turn in their graves with her new job writing painfully historically inaccurate scenarios for Foremost Studios, in between wrangling their leading lady out of the arms of her army of amorous suitors.

So when one of Kitty's old flames, renowned film director Ernst Zapolya, calls Emma and tells her it's imperative he meet with Kitty that morning, she's not surprised. Until, that is, he adds that lives depend on it. Ernst sounds frightened. But what can have scared him so badly - and what on earth does cheerful, flighty Kitty have to do with it?

Only Ernst can provide the answers, and Kitty and Emma travel to the set of his extravagant new movie to find them. But the shocking discovery they make there only raises further questions . . . including: will they stay alive long enough to solve the murderous puzzle?
