Catherine calls Yorkshire Police to report Ann's kidnapping and calls it a "tiger kidnap." This is incorrect, as Ann's abduction was a regular kidnapping for ransom. A tiger kidnap is when someone is abducted, but instead of asking for a ransom, the kidnappers instead demand someone commit a crime for them, such as robbing a bank or setting off a bomb. Tiger kidnaps are very common in Ireland and were used by the IRA, when they would kidnap someone to coerce their loved one to plant a car bomb.
