I've read Malcolm Gladwell's books, Blink and Outliers.

Those books were completely engaging, interesting and compelling to the point that I could not put them down.

Those books are not Grisham yarns or Clancy tales of page-turning fiction, but are books of journalistic exploration, discovery, understanding and what-is-learned-next non-fiction.

I have never read non-fiction books that are as enthralling as Gladwell's work.

Gladwell has mastered his prose style. 
Gladwell has also mastered his storytelling craft.
He is a complete artist in every sense.
He weaves these true life accounts and histories wonderfully and tacitly, moving you through the lives of these people and moving you through these unremarkable now remarkable events.

What The Dog Saw is a collection of Mr. Gladwell's work from his efforts for The New Yorker.
Each chapter is an essay discovered and written for the magazine. This book provides numerous subjects as opposed to one main, overriding subject pursued in his other books.

These essays and articles are written extremely well and are very interesting. As always, the people, places, facts, misconceptions, truths and far-reaching results of all of these ingredients are quite incredible. "Ronco", women's hair coloring and the Pill all provide deep subject matter for Mr. Gladwell to delve into.

But - for me, this book did not keep my interest.

After thinking it over, I think I would enjoy reading Mr. Gladwell researching, discovering and crafting these subjects into one of his full-length works. He is so good at all of the above ingredients, it's a let down to only get small pieces explored and end up with small pieces written. I just wanted Mr. Gladwell to go all out on these subjects - writing for a magazine format does not allow that.

That may be where the rub is for me.

This is not a Malcolm Gladwell book.
This is a great collection of Mr. Gladwell's New Yorker articles.

To tell you what this book is about would result in you not having to read it.
You would also completely miss out on Mr. Gladwell's fascinating approach to following the trails of research and approacable, sharply insightful writing.

I can try and explain this book in a series of exclamations as examples of what you will experience while reading:

No kidding?
Duh.
Oh, my.
I never noticed that.
You're kidding?
No, I don't.
No, we don't.
Yes, that does.
I never thought about that.
Dang.
Gasp.
Now I feel silly.
Well, how about that...

If you have read any of Mr. Gladwell's books, you will enjoy this book as well.
If this is your first go at a Malcolm Gladwell book, I will bet you will enjoy it and then promptly seek out his other works.

Don't Blink.
Well, I think you most certainly should Blink.
