Date: February 1920 (from opening caption). The episode takes place over about three weeks.

Goof: Hudson reads out James' letter to The Times. The letter starts with: "Dear Sir," but letters in The Times have traditionally always started with just "Sir". (1'03")

Rooms: This is our first look at the redecorated morning room. Orange-brown striped wallpaper occupies most of the walls, with the space above the fireplace painted orange. The laurel-leaf design above the fireplace remains in its old light-blue colour. Sir Geoffrey Dillion doesn't seem to like the new look!

Goof?: Concerning the idea of James standing as a Conservative MP, Sir Geoffrey says: "Well, there'll be a by-election quite soon – Rotherhithe. Old Harry Wetherall, who contested the seat unsuccessfully for years, died last month." Quite possibly it's just the scripting, but this makes it sound like the death of an unsuccessful candidate has caused a by-election to be called. But it would be the death of the sitting/current member that would cause such a by-election. (7'10") (Thanks to Neil Gray for sending this one in.)

Goof?: The conversation in the morning room lasts longer than six minutes but the time on the clock on the mantelpiece never changes (OK, I suppose it could be broken or not wound...) (9'18") (Thanks to Tony Murray for this one.)

James background: He stands for a by-election in Rotherhithe East – a cast-iron Labour seat. He loses by a large margin, but nevertheless manages to reduce the Labour majority by 639 votes compared to the earlier general election. He decides not to stand again.

Rose background: She is at Southwold for this episode as an aunt has passed away (12'11"). This may, or may not, be the same aunt as mentioned in For Love of Love and/or Married Love and/or The Wages of Sin.

Edward background: After leaving 14 months ago (i.e. about December 1918), he and Daisy are living in a dilapidated flat in Camberwell (9 Stockwell Road). His door-to-door selling "didn't work out" and he is unemployed. During this episode, Virginia takes him back on at 165 as chauffeur and valet to James (at £40 per year).

Daisy background: Because of their living conditions, Daisy lost her baby at the six-month stage (about September the previous year). She says she can still have another child. During this episode, Virginia takes her back on at 165 as head houseparlourmaid (at £35 per year). She gives the couple the room over the garage/stable.

Goof?: As Edward and Daisy storm out of 165 after the argument, they forget to ask for their hats and coats (19'51"). This is probably simply a dramatic compromise to provide a stronger end to the scene.

The location for the two outside scenes in this episode (James' speech, and the Bellamys' arrival at the mission) was Swan Road, off Brunel Road, in Rotherhithe itself. The area is now completely changed since the 1970s.

Goof: About Daisy's shoes, Angela Baddeley: "Even if they are comfortable, there's no need for... not to take your weight off them." (32'34")

Goof: Lily is using a sewing machine, but the material does not move forward as she sews (33'10"). When asked to clear away, she removes the fabric from the machine without cutting any thread (34'00").

Rooms: This is our first look at the flat over the mews garage since the days of Thomas. It now seems to have a small en-suite kitchen.

Goof: The camera jolts as it runs over something on the floor (38'46").

Goof?: Daisy's shaved armpits probably owe more to 1975 than 1920 (39'42").

Goof?: It's difficult to see on anything less than an ultra-clear copy of the episode, but there seems to be a sign at 40'19" which reads "Queen Mary Seamens' Mission" with the apostrophe thus.

Goof: If you look closely behind Jack Le White at 44'17" you can see the front of a camera swinging round and a member of studio personnel in a white jumper.

One of the hecklers at the back of the hall is Derek Martin who became much better known later for his long-running role as Charlie Slater, patriarch of the dreaded Slater family, on the BBC soap Eastenders.
