It took me several grueling months to make it through this book. I am quite fond of Priestley's other writing, so I thought this was a sure bet--the book that made him famous, it says on the cover! Well, reading this book is like being stuck at an old lady's house, being pumped full of camomile tea and flavorless biscuits, and hearing the same dim-witted stories again and again about her travels all around England in her youth back when she was theatrically inclined. This isn't a particularly intelligent lady, mind, and she has a real tin ear for dialog...
Nothing much happens for the first 200 pages or so, other than the main three characters being introduced. Almost none of the information in the first third of the book will be useful to you in the rest of the book. It could have been done in 30 pages, easily, without any loss of steam or impact. Then we meet the rest of the characters. They all have the same tedious, chatty manner of speaking, and the only difference between them is whether they speak some 'orrible phonetically spelled English regional dialect or the straight middle-brow variety.
The middle of the book is sheer tedium. Just when you think something interesting happens, the story dissipates. It sort of makes sense for a road novel, which this essentially is, but let me just tell you it ain't no Odyssey. Reading this part of the story, where the theater company is formed and they start having their "ups and downs", is where I really started to lose hope.
The end is dull and predictable. Nothing happens that you couldn't have anticipated after reading the first half of the book. By the time I realized this, I started reading at a faster clip, skipping much of the redundant, dull dialogues and paying attention only to major events. They are contrived and tedious, and the book at this point seems really dated, without any sort of relevance to the modern reader.
Do I regret reading this book? Yes. Do I wish I had spent my time on something else? Absolutely. Would I wish it on my worst enemy? Probably not. I am not that cruel.
