Allison Abernathy ("Ally" for short)
Ally grew up in a police family. Just like her great-grandfather, her grandfather and father before her she was always destined to join the police. Police blood ran through her veins. When Ally put her mind to something, she would achieve it and generally let nothing stop her in her tracks. Even growing up, where she focused on boxing, it was never enough that she won the best titles; she wanted to be the best. She always felt she had to go one step further. She was the best at the police school, always attentive, focused, and determined. She graduated with honors and was immediately assigned to the criminal department in Glasgow.
Her streak of success was interrupted when she worked with the Polish police to capture the Cryptic Killer. It was then that she was seriously injured, and the perpetrator fled. In the hospital, she met her current husband, with whom she has two sons.
After a few years, she returned to the service and has since only dealt with smaller, less complex cases. However, she is still an uncompromising investigator, while at home, she is always a caring mother and wife.
Steve "Old Dog" Kowalski
Old before his time, even as a young boy playing games with his friends, Old Dog, knew he would be a police officer. He hadn't even finished his first year at the academy when he caught a dangerous criminal; this was to be the first of many during his successful career.
Eventually, he became the Polish police commissioner. While his career has been a success, his personal life has sadly not. He has always been known as a "ladies man", which may be true, but he is actually a loner and stuck in his ways.
"Married to the job", he spends his evenings in his favourite armchair, sipping a cup of black coffee as black as coal, and listening to his favourite blues records, while he goes over his cases.
His devotion to solving them has never been tested as much as it was by the Cryptic Killer. With this killer back on the loose, he and his Scottish partner won't stop until this mystery is solved once and for all.
