I assume you mean which of the Wainwright Pictorial Guides would be best.
If you look at a map of the lake district you will see that Kendal is right on the edge of the Lakes and has no large hills round it so it was not even included by Wainwright in the Pictorial Guides.
And it has to be said that even Windermere is still rather on the edge of the lakes so there is almost near Windermere in his books.
Book 2 - The Far Eastern Fells covers the area NORTH EAST of Windermere (the high street range)
Book 1 - The Eastern Fells covers the area NORTH of Windermere (Hellvellyn etc)
Books 3 and 4 (Central Fells and Southern Fells) cover the area WEST of Lake Windermere, but you are now starting to get a fair way from Kendal and Windermere.
When he was getting older he did write a book called the Outlying Fells, these were all the smaller hills that he could not be bothered to walk up when he was younger, and it does have a LOT of walks in the south east area around Winderemere and Kendal, see here:
