The investigation into the attack on Tanya Fisher continues, with DS Debbie McAllister and DI Will Elvins from MIT having strong suspicions about her ex-husband, TDC Brandon Kane. As PC Cathy Bradford prepares to flee the country, she receives a phone call from PC Polly Page telling her about Kane's questioning. As suspicion begins to fall on her, Bradford arrives at the station and taking a leaf out of DS McAllister's book, tells the investigators that Brandon couldn't have attacked Tanya - he was beating her up at the time, and she is pregnant with his baby.
