'One of the finest storytellers of her era and genre... [From the Mixed-up Files of Mrs. Basil E. Frankweiler] is a story of discovery and self-discovery' - Washington Post

'Mischievous and metropolitan... A wild rumpus... Japes abound' - New Yorker

'E. L. Konigsburg is one of our brainiest writers for young people, not only in the considerable cerebral powers she brings to her books but in the intellectual demands she makes on her characters' - The New York Times

'A work of genius' - Katherine Rundell

'In the US... [Konigsburg] is pretty much required reading for anyone under the age of 11 and, indeed, over, too, and I strongly urge everyone who falls into either age group to discover her forthwith... From the Mixed-up Files of Mrs Basil E Frankweiler... dominated my imagination in the way only a really good book can wholly inhabit the head of a child... Re-reading From the Mixed-up Files of Mrs Basil E Frankweiler,... it was, if anything, even more wonderful than I remembered' - Hadley Freeman
