E.R. Punshon was born in London in 1872.
At the age of fourteen he started life in an office. His employers soon informed him that he would never make a really satisfactory clerk, and he, agreeing, spent the next few years wandering about Canada and the United States, endeavouring without great success to earn a living in any occupation that offered. Returning home by way of working a passage on a cattle boat, he began to write. He contributed to many magazines and periodicals, wrote plays, and published nearly fifty novels, among which his detective stories proved the most popular and enduring.
He died in 1956.
