A very good episode, with shades of Bond within. From the clever gadgets like a homing beacon concealed in a pipe, to an early meeting with a 'Q' like figure, one can see why Patrick McGoohan was first offered the role of James Bond.
Cleverly written, with a twist of an ending that foreshadows some of the writing in The Prisoner. A good deal of McGoohan's troupe is seen in the episode, and he performs his stock drunk character quite well. The only drawback is the use of English actors for Asian characters, though many true Asians are used throughout.
