If you're a fan of the locked room troupe, then this is a very special book for you. The Invisible Host, by Gwen Bristow and Bruce Manning, is a 1930 murder mystery that may look very familiar to fans of the murder mystery genre.
Picture it, a group of people are invited to a penthouse in a tall building high above the city of New Orleans. There's a thunderstorm brewing outside as well as inside. As the guests arrive they all seem to know each on in some way, but when their unknown host comes to them through the radio, things take a sudden turn for the worst. They find themselves locked in the penthouse, unable to escape. The doors have been charged with voltage, the fire sprinklers have been filled with poisonous gas, and it seems that every hour, one guest will end up dead. By morning, all the guests will be dead, unless they can match wits at the host's demented and murderous game!
If this sounds familiar, it's because it is. Nine years after this book was published, Agatha Christie penned her most famous novel, And Then There Were None, which has many of the basic elements that this mystery has. Whether or not she stole the concept is unknown, but it's safe to say that Christie's is a true masterpiece.
But I don't think we as readers should base our judgments on the work it's mostly compared to. On its own, The Invisible Host is a fun and demented read. If you're looking for something realistic, this book isn't for you, but if you allow yourself to let loose and be invited into the warped narrative, it's a fun ride. It reminds me more of the films Clue, Murder by Death, or the Saw franchise (only far less gory). There's an element of fun to this novel, that I think is either overlooked or underappreciated.
The backstory to this book is fascinating. Bristow and Manning were newlyweds, both worked as reporters and decided to spend their nights devising this novel, their first, together. Before it was even published, famous playwright Owen Davis, adapted the story into a murder mystery melodrama play, called The Ninth Guest, which was eventually turned into a film with the same name in 1934. I'd be curious to read the play script. I think it would make for a wonderful high school or community theatre production.
The main issue I had with The Invisible Host is the pacing. It felt at times to run really smoothly, but other times it dragged on account of the explanations were drawn out. I think if it had been more back and forth and stayed consistent in its pacing, it would have made for a more readable story. Other than that, I think it's a fun read and very interesting considering its age and comparison. For fans of locked room mysteries, over the top mystery movies, The Invisible Host is one you'll enjoy for sure. My rating - 4/5
