Slow Horses follows the story of a group of British intelligence agents who serve in a dumping ground department of MI5 called Slough House after the big mistakes they've made that resulted in the end of their mainstream careers.

Chicago Fire
No job is more stressful, dangerous or exhilarating than those of the Firefighters, Rescue Squad and Paramedics of Chicago Firehouse 51. These are the courageous men and women who forge headfirst into danger when everyone else is running the other way and whose actions make the difference between life and death. These are their stories.

Ghosts
Samantha and Jay throw caution to the wind when they convert their recently inherited country estate into a bed-and-breakfast. Call it mislaid plans. Not only is the place falling apart, but it's also inhabited by spirits of previous residents -- whom only Samantha can see and hear. Ghosts spins the funny, heartfelt story about a newfound dream that reveals connection and self-discovery aren't just for the living.
