The unusual murder of a prominent scientist and his assistant is clearly a case for Mr Steed and Mrs Peel. But what is the connection with a vial of unusual vegetable oil? Who is the mysterious Koslov, who seems to be selling the oil? Why were the victims blinded before they were killed? Then if matters weren't complicated enough, the Torchwood Institute gets involved!

Supergirl Returns #10 - An ordinary day in Cardiff... in which Torchwood has to deal with robot assassins, alien children, a superhero and threatening phone calls from Sarah Jane Smith. Torchwood / Avengers UK / SJA / DC Movieverse crossover.
