Robin Sumner is lost in Whitechapel, his mother and uncle having been killed by Nathaniel Dove. Luckily he walks straight into the path of the newly demoted Frank Thatcher - giving him the opportunity to prove himself of use to Reid, Jackson and Long Susan. The opportunity to find fresh evidence is too good to miss, but can Reid build the case before Augustus Dove covers his brother's tracks?
