Finding a title for my historical novel  A Jacketing Concern was a matter of serendipity.

Because the novel was about a climbing boy — as sweep’s apprentice — my working title had been The Climbing Boy. However, quite by accident I came across a phrase that much better encompassed what the book was about: a jacketing concern.  It comes from the Flash tongue of the criminal underworld of early 19th century London. It was used in the city’s ‘rookeries,’ the poverty ridden haunts  where the poor and criminals lived side  by side.
