Saul Bellows once wrote: "There is only one way to defeat the enemy, and that is to write as well as one can. The best argument is an undeniably good book."

Notice what’s wrong? Some might not, but keen-eyed teacher Alex Games spotted a glaring error in this quotation printed onto a window at Swiss Cottage Library.

Alex wrote to the Ham and High last week to point out that the the famous author’s surname should not have an S.

The teacher and writer said: “Swiss Cottage Library, that icon of 1960s architecture, has had the bright idea of decorating its windows with quotations from famous writers and personalities.

“A good idea, surely. What could possibly go wrong? Well, the trouble is they seem not to have heard of one of the greatest novelists of the 20th Century.”

This “jaw-dropping” mistake had reportedly been pointed out to staff at the library, but had not been corrected.

The Pulitzer Prize winning author Saul Bellow is best known for works including Herzog and The Adventures of Augie March.

But it seems no amount of critical acclaim can save you from becoming the victim of wayward spelling.

A Camden Council spokesperson apologised for the error yesterday (March 20) and said that it would be corrected immediately.
