Piranha to Scurfy (Storycuts) [EPUB ebook] 

In a house filled floor to ceiling with books, a lonely middle-aged man scrutinises new publications for editing errors. He is obsessive, writing angry letters to each author he finds fault with. Books are his life – and in an unexpected way have led a terrible guilt to fester inside him. Just when he thinks that all is buried and forgotten, a work of fiction with uncanny resemblances to his own story sends him back to the dark precipice.Part of the Storycuts series, this short story was previously published in the collection Piranha To Scurfy.
