The late 1960s spy-fi show "Department S" was one of the best of ITC's impressive output. Dealing with the most bizarre cases that other agencies had previously failed to solve, the Department was a kind of forerunner of shows such as the "X Files".
Somewhat ahead of its time, it had a black head of department, Sir Curtis Seretse (Dennis Alaba Peters), a high-ranking diplomat with invaluable connections. The field team leader was the American Stewart Sullivan (Joel Fabiani), a professional, cool and somewhat cynical man of action, who would see each case through to the end, no matter how many villains he needed to chase down and knock out to achieve that, or how many attempts on his life or threats of political consequences he had to survive in the process. The novelist Jason King (Peter Wyngarde) was a man of overbearing imagination, who would use the fictional cases of his novel hero, Mark Caine, as inspiration for solving the Department's cases - and vice versa. His exact opposite was the computer expert Annabelle Hurst (Rosemary Nicols), who preferred the analytical approach and was constantly feeding data into her computer, "Auntie". However, she wasn't completely beyond emotion, and there was a subtle romance of sorts going on between her and Stewart.
Different as they were, the principals made a great team, and with their various approaches combined, they always managed to solve even the most baffling cases. The actors were excellent, and most of the stories were quite original. A very enjoyable show - it's a real pleasure to (re-)view this piece of classic cult television!
