Plot summary
When Kayla Stark reports that her two-year-old son, Ryan, has been taken from a high-street merry go round, Brooks and Devlin suspect that her ex-boyfriend, who is also the child's father, may be responsible. However, upon examination of the CCTV footage, the pair discover that the child was never on the merry-go-round, and that the buggy Kayla was pushing at the time was empty. Suspicion then turns to Kayla's current partner, and when the boy is found dead in the airing cupboard at his flat, Brooks and Devlin believe they have their man. However, without any evidence proving whether Kayla or her boyfriend killed Ryan, Thorne and Phillips must decide which guilty party to prosecute.
