The second series in Granada's 'Mr Rose' cult crime/suspense trilogy, It's Dark Outside saw William Mervyn reprising the role of the charismatic Inspector Rose, first introduced in The Odd Man just six months previously and re-emerging in slightly mellowed form in the final series, Mr Rose.

It's Dark Outside follows the sharp-witted and memorably prickly detective as he tackles a fresh batch of cases. Assisting Rose in Series One is the more amenable DS Swift (played by a youthful Keith Barron), with John Carson as solicitor Anthony Brand and June Tobin as Brand's journalist wife, Alice; Series Two sees Rose verbally sparring with newcomer DS Hunter, played by cult favorite actor Anthony Ainley.

Although two series of It's Dark Outside were made, the second was thought completely lost until research for this set unearthed two episodes which still existed on film. Newly transferred, these episodes have been included here alongside all those from Series One.
