Over at: The State Library of NSW, there's a delightful little short story, IN THE COMPANY OF RATS, by Sulari Gentill featuring a very young version of her redoubtable character Rowly Sinclair, who even at the tender age of 14 was a trial to his family, with all the makings of the kind, generous and decent man he'd become, with an eye for an investigation even then.
The story was originally published in Openbook in 2021 and is a lovely little reminder (or introduction) to the historical series that the author became so well known for.
