This is the last of the black-and-white episodes. It was originally due to be transmitted after Magic Casements (see the on-screen dating) but the two episodes were switched in transmission order to keep the five black-and-white episodes together.

This is the "rarest" of all the UpDown episodes. It has only been shown twice on the main five TV channels (and only the first of these was a networked showing). Every other episode has been shown at least three times. It was also the only episode omitted entirely from the novelisations.

Date: October 1906 (from opening caption).

Goof: Patsy Smart says "Mr Hudston" again (see also On Trial) (0'44").

Rose background: Rose still has (unnamed) family at Southwold (Lady Marjorie's family estate), whom she is visiting in this episode.

Goof: Gordon Jackson calls out to "Emily, er, Mary" (1'08").

Susan Penhaligon (Mary Stokes), making an early (but not her first, as is commonly asserted) television appearance here, went on to become a well-known film and TV actress.

First appearance of Edward, played by Christopher Beeny (1'48").

Rooms: The light switch next to the servants' hall door makes a return. The house is clearly now wired for electric light as there is also a switch (used by Richard at 10'27") to the right of the morning-room door, as well as an electric desk lamp (8'43).

Goof: You can hear the gallery cue the bell to ring (4'03").

Rooms: Once again a writer seems to not know that 165 has a back staircase and a servant uses the main front stairs instead (9'30").

Goof: Can you really open and close a hot range door with bare hands? (18'10")

Goof: At 21', Edward gives Emily exact details of the earlier conversation between Hudson, Mrs Bridges and Roberts. But Edward was helping Mary upstairs when the conversation occurred (and there doesn't seem to be anyone else around who would have related it to Edward). (Thanks to Arne Andersen for sending this one in.)

Emily calls Edward by the surname Randall (21'47"). The name would subsequently change to the more familiar Barnes.

Nicholas Young (Myles Radford) is better known for his long-running role as the po-faced John, leader of The Tomorrow People (1973-9), a children's sci-fi show.

Goof: There's a more-obvious-than-usual boom microphone jutting into the top of the shot at 31'24". This problem was quite common in TV programmes of the day. However, to be fair, back then it would have been less obvious to the viewer because the tube/CRT TVs in use lost quite a bit of available picture on all four sides of the screen (called overscan). Modern flat-screen TVs show more of the picture and so incursions such as this are now more obvious. (Thanks to Jaap Smolenaars, who spotted this.)

First appearance of Sir Geoffrey, played by Raymond Huntley (33'30").

Goof?: Raymond Huntley: "...unless I can make them see reason to put you in the public pillory." Doesn't he mean, "not to put you in the public pillory"? (37'38")

Richard background: He is working on a book on the life of Conservative politician, Arthur Balfour (who was the British prime minister 1902-5). Sir Geoffrey jokes that, given Richard's predicament, a life of Gladstone would be more appropriate (Gladstone, who was prime minister a number of times in the late 1800s, was rumoured to have toured night-time London and taken an unusually close interest in helping "fallen women", leading to many nudge-nudge-wink-wink rumours in society).
