The Guest House - ‘A tense spin on the locked-room mystery’ Observer

KEEP YOUR FAMILY SAFE. WHATEVER THE COST... Jamie and Victoria are expecting their first baby. With a few weeks to go, they head off for a final weekend break in a remote part of the North Pennines. The small and peaceful guesthouse is the ideal location to unwind together before becoming parents. Upon arrival, they are greeted by Barry and Fiona, the older couple who run the guesthouse. They cook them dinner and show them to their room before retreating to bed themselves.
The next morning, Jamie and Victoria wake to find the house deserted. Barry and Fiona are nowhere to be seen. All the doors are locked. Both their mobile phones and car keys have disappeared. Even though it's a few weeks early, Victoria knows the contractions are starting. The baby is coming, and there's no way out.
