fashionable ['fxSnqbl], wealthy ['welTI], charity ['CxrItI]

She "did" for fashionable Lady Dant, the wife of a wealthy industrial baron, who maintained a flat in London as well as a country manor — Lady Dant was always getting her picture in The Queen or The Tatler at hunt balls and charity affairs, and this made Mrs. Harris proud.

All of these establishments Mrs. Harris looked after quite on her own (за всеми этими домами миссис Харрис смотрела/ухаживала полностью сама: establishment — учреждение; дом; to look after — ухаживать/заботиться).

couple [kApl], divorcee [dI"vO'sI], valuable ['vxljuqbl]

There were others: a White Russian Countess Wyszcinska, whom Mrs. Harris liked because she was divinely mad; a young married couple; a second son, whose charming flat she loved because there were pretty things in it; Mrs. Fford Foulks, a divorcee, who was a valuable mine of gossip as to what the idle rich were up to; and several others, including a little actress, Miss Pamela Penrose, who was struggling to gain recognition from her base in a two-room mews flat.

All of these establishments Mrs. Harris looked after quite on her own.

Yet she was not without assistance and someone to fall back on in case of emergency (однако она не обходилась без поддержки того, /к чьей/ помощи /могла/ прибегнуть в случае крайней необходимости) in the person of her friend and alter ego Mrs. Violet Butterfield (в лице ее подруги и единомышленницы миссис Вайолет Баттерфилд), like herself a widow and a char (такой же, как она сама, вдовы и уборщицы), and inclined to take the gloomy aspect of life and affairs wherever there was any choice (и склонной воспринимать жизнь и ее дела с мрачной стороны по любому поводу: «брать /именно/ мрачные стороны жизни и дел, где бы ни был выбор = когда был какой-либо выбор»; wherever — где бы ни, при любых обстоятельствах).

Mrs. Butterfield, who was as large and stout as Mrs. Harris appeared to be thin and frail (миссис Баттерфилд, которая была настолько же крупной и крепкой, насколько миссис Харрис казалась худощавой и хрупкой), naturally had her own set of clients, fortunately likewise in the same neighborhood (конечно, имела собственный набор клиентов, также, к счастью, в том же районе; neighborhood — сопредельность, соседство). But they helped one another out (но они выручали друг друга; to help out — выручать) with a nice bit of teamwork whenever the necessity arose (с приятным взаимодействием = с завидной слаженностью в работе всякий раз, когда возникала необходимость: to arise; teamwork — коллективная работа; согласованная работа; совместные усилия; взаимодействие; team — команда, коллектив).

If either one of them was ill or had pressing business elsewhere (если одна из них была больна или имела срочные дела где-либо в другом месте; to press — жать, нажимать; торопить), the other would manage to pinch enough time from her clients (другая умудрялась выкроить достаточно времени от /обслуживания/ своих клиентов: to pinch — щипать; урезать/брать понемногу) to make the rounds of the other's customers sufficiently to keep them quiet and satisfied (чтобы сделать обход клиентов другой достаточно, чтобы сохранить их спокойными и довольными = обеспечить их покой и удовлетворенность).
