The content of this book is really fascinating from a modern, privileged point of view. The stories of the various families the author looks after form the core of the book, chronicling poor living conditions and other unusual circumstances which are quite shocking by today's standards. We see everything through the eyes of the author, a health visitor who by virtue of her job sees into many disadvantaged lives. However, this comes with the obvious limitation that she can often only offer a brief glimpse into a family's circumstances, unable to elaborate on how things came to be that way and remaining largely mystified by what occurs outside her jurisdiction. This can cause the stories to feel incomplete, which may be frustrating if you are looking for a resolution to each of her families' or patients' tales.
Another flaw is a shortage of detail. I would have liked to learn more about the healthcare policies of the time, most of what she does at the clinic aside from drinking tea, what the nappy test is for and what other medical tests/services she carries out, what's in her bag, what she teaches at the mothercraft clinic, and so on and so forth. She focuses far more on the social worker aspects of the job than anything else, and so this is not a book for people who want specific information about healthcare in the late 1950s, the finer details of being a health visitor, or '50s attitudes to dysfunctional families - at best you can get a general impression and make some assumptions from the text.
It's also not for people who want a very personal memoir, as the focus is much more on the families she visits than on herself. It's hard to get a feel for her personality, her passions and what she does in her spare time, and it's even harder to understand her relationship with her partner Alan or how her relationships with her colleagues develop. Otherwise, if your interest is a little less specific and you are looking for memoirs of a working woman in the 1950s or insight into social work and a snapshot of disadvantaged people's lives at the time, this book may fulfil your needs rather well.
Aside from that, I feel that the main flaw is in the formatting and editing. The book is presented in a form I initially thought to be a diary, but it is in the present tense as though we are enjoying the author's narration as the events occur. One therefore expects everything to proceed in a chronological order, and thus it is quite disorienting when the author includes a flashback or aside. Once there is even a flashforward occurring four years ahead and curiously appended to a normal chapter 3/4 of the way through the book; the author seems to have thought it worth cramming in not because it is particularly relevant but because she thinks it's a good story - which it probably could be, in the right context. This book is not the right context, but a sequel might have been.
In addition to the aforementioned complaint, portions of events have been judiciously excised as though to preserve some form of narrative tension, but it's not guaranteed that it will ever be paid off later. For example, on one occasion she visits a house where she meets an expectant mother's husband for the first time. He appears, acts very oddly and leaves again, and the chapter ends immediately afterwards, a sort of cliffhanger that is never resolved. We are given no suggested explanation for his actions, nor any indication how the rest of the visit went or if the author ever discussed her husband's behaviour with his wife. Hopefully you make the assumption he has a mental disability as the author seems to take this for granted. These occasional swerves and random time skips contribute to a sometimes uneven pace, adding another layer of frustration to that caused by the unavoidable lack of resolution to some of the narratives.
Last of all, it is worth noting that the Orion paperback edition I read was poorly edited and proofread in places. I didn't see any mention of this in my brief look at other reviews, so I'm wondering if the text somehow got mangled between editions. Aside from the fact a good editor could have given the book a better polish, there are a number of typos as well as instances of extraneous punctuation, missing commas, and a few jarring comma splices. The author otherwise seems well acquainted with the correct use of the semi-colon so the comma splices were quite puzzling. I wouldn't say the proofreading job was completely disastrous, but for a professionally published book it is definitely subpar, tending towards self-published proofreading quality. I own quite a few Orion books and can't recall any with more than two or three typos, so perhaps this one was just an unfortunate blip.
Now - while my review has almost exclusively focused on the negative, I do feel there are a lot of good things to say about this book. As others have noted, it's a little like 'Call the Midwives' in non-fiction form (minus any delivering of babies). It's able to give a broad view into many homes and the stories we find there are very compelling. Some do end uncertainly, but others end with triumph and hope. All in all it's very easy and pleasant reading, the sort of book you can happily devour in one or two sittings, and if the author does ever write a sequel I would be pleased to have the opportunity to read it.
