The Hamilton Public Library has a copy of Modern Shorts with a handwritten notation on the title page beneath the name of the last author listed, Leslie Hamilton, that says "pseudonym of Henry Bolton". A check of Vernon's City of Hamilton Directory from the early forties tells us:
- the only Henry Bolton listed is a salesman,
- there is no listing for Beaver Publications, and
- the only Leslie Hamilton listed is an employee of Robert Duncan & Co. who printed Modern Shorts.
The biography of Leslie Hamilton in Modern Shorts says very little but there is a picture of a very "authorial" man.
