This is the first of the Wallace stories which were extremely popular at the time. If they're all up to this standard, then their re-release is long overdue.
If you enjoyed the crime fiction of the era, [[The Crime at Black Dudley by Margery Allingham|Campion ]] being a case in point, or more so if you followed Hannay's adventures beyond The 39 Steps, then you'll love this. I'm now off to read book 2.
