The Night of Dagon

When Devlin Macky stole the Silver Bluebell from the Natural History Museum, he got far more than he bargained for. Mordred Haddonfield wasn't the most benevolent employer. The man was evil. Macky knew that, but he also needed the money. The Bluebell was more than a priceless artifact. It was a summoning device. Haddonfield wanted to use it to resurrect a cosmic, ancient evil - buried now for more than two thousand years.
