The Urgent Hangman [EPUB ebook] 

CALLAGHAN turned the corner into Chancery Lane. A gust of cold wind met him, blowing back the flaps of his not-so-clean raincoat, sending the rain through his threadbare trouser legs.
He was five feet ten and thin. He had sevenpence halfpenny and a heavy smoker’s cough. His arms were a little too long for his height and his face was surprising.
It was the sort of face that you looked at twice in case you’d been mistaken the first time. The eyes were set wide apart over a long, rather thin nose. They were a light turquoise in colour and seldom blinked. His face was long and his chin pointed. He was clean shaven and women liked the shape of his mouth for reasons best known to themselves.
