"Dear Bill Liversidge,
Thank you for sending us A Half Life of One, which has now been to a reader and given due consideration. Although our reader found it interesting, I regret we are unable to accept it for publication.
Macmillan receive many thousands of manuscripts every year so unfortunately it is not possible to respond personally to every author.
Because we receive so many mss and are able to publish only a small percentage, rejection does not automatically imply anything about the quality of the work we are unable to use.
There are many reasons why a book may not suit our lists. We may have other, similar material in production, we may be oversubscribed with good submissions during this season, we may have decided not to publish books on certain themes, etc.
Unless you have asked us to return a typescript manuscript to you, we will now permanently delete any electronic files we have relating to your book.
Thank you for contacting us, and good luck with your writing.
Will AtkinsCommissioning Editor, Macmillan New Writing"
