Mr. Poskitts Nightcaps: Stories of a Yorkshire Farmer

1910 Eveleigh Nash, 1935 Eldon Press

The premise for this book is that before retiring to bed each night, Yorkshire farmer Mr Poskitt liked to tell a little tale, or ‘nightcap’. J S Fletcher has thus written down and collected these 14 short stories. Whether or not that part is true, I have no idea, but this is a great collection of stories about rural Yorkshire lives at the start of the 1900s. There’s a spooky tale, stories of money grabbing and arguing over wills, ownerless pigs running through the village causing havoc, broken hearts and jealous sweethearts, and penny pinching misers and men out to make a fortune.

The Three Days Terror

1909 John Long , 1927 Edward J. Clode
A science fiction thriller in which a detective tracks down a group known as the Dictators who use a ray to destroy whole districts in order to hold Britain ransom. Somewhat of a departure from Fletcher’s classic mysteries. However, mystery and intrigue are woven into this tale.
