Awards: This episode won the director, Bill Bain, an Emmy for Outstanding Direction in a Drama Series.

Date: In the days leading up to Britain entering WWI – 4th August 1914 at 11 p.m.

Ruby background: She can now read quite well and manages words like "broché", "corsage" and "tulle" when reading from the newspaper (1'41" & 3'31").

Hazel background / James background: They are now sleeping in separate rooms (5'21"). James works for Jardine Matheson ("Jardines") (9'09").

Goof?: I am confused as to why Rose thinks a Serbian archduke has been killed (Franz Ferdinand was Austrian). Maybe this is to indicate the servants' ignorance of events overseas? (4'14")

Goof: No British dreadnought warship of the time carried 16-inch guns (5'33") (Thanks to George for this observation.)

Goof: Frank Middlemass tears the newspaper cutting as he takes it from his wallet (12'23").

Mrs Bridges background: Mr Lyons enquires about whether there is a Mr Bridges. Hudson replies: "To my certain knowledge, Mr Lyons, there has been no Mr Bridges – the title 'Mrs' being the usual honorarium enjoyed by cooks of a certain class." (cf. Why is Her Door Locked?) (14'44")

At 15'21" Hudson says to Mr Lyons, by way of small talk, "Well, Carpentier gave the American a good beating the other evening." This is a reference to the World White Heavyweight boxing match between the Frenchman, Georges Carpentier, and the American, Ed "Steamboat" Smith, on the 16th of July this year. The match was won by Carpentier but only after the controversial disqualification of the American on a technicality.

Goof: Meg Wynn Owen picks up her cup by the sides, not the handle – very unladylike! (18'42")

Elizabeth background: "Children" (plural) are mentioned, so Elizabeth has presumably now had one or more children by her second husband, Dana (26'15").

Mr Hudson background: He had a great-great-uncle who fought with the highlanders at the battle of Waterloo (28'07").

Two sets of location work was done for this episode. Firstly, at Herne Bay on the Kent coast. Secondly, at Knowlton Court, near Canterbury, in Kent, for the scenes of the house party that Georgina attends. These two shoots were the first work that Jacqueline Tong and Lesley-Anne Down did for the series (the studio material was recorded some time later).

The pierrots sing a 1914 song called Gilbert, The Filbert (music: Herman Finck / lyrics: Arthur Wimperis). Afterwards, Hudson does a rendition of the famous 1911 J Milton Hayes poem, The Green Eye Of The Little Yellow God.

Goof: As Hudson is called to the stage by the pierrots, television aerials are visible on the buildings behind him (and on other shots from this position throughout the scene) (37'12").

Goof?: There is an extra in the show's spectators who seems to be wearing rather un-1914-like spectacles (38'26" and 39'15"). (Thanks to Lois A Graham for this observation.)
