Despite this most tragic personal loss, Muddock still managed to see his sons as English "gentlemen" whose deaths were part of the great sacrifice the nation was making.
Most of Muddock's stories featured his continuing character Dick Donovan, the Glasgow Detective, named for one of the 18th Century Bow Street Runners.
Muddock also wrote true crime stories, horror, and 37 novels, most as "Dick Donovan".
The town of Flin Flon takes its name from the lead character in a 1905 paperback novel by Muddock.
In The Sunless City, Josiah Flintabbatey Flonatin pilots a submarine through a bottomless lake.
When he discovered a rich vein of almost pure copper, by a deep lake, it reminded him of the book.
