Dial 999: PC Thirteen Investigates.
UK Hardback Christmas Annual.
A colleague at work brought this 1953 annual in for us to look at. It seems to stem from a BBC radio series (possibly) of the same era.
It is all text stories with spot illustrations by F. G. Moorsom (who appears to specialise in uniformed police stories from that era.)
Really great book. Here is the cover along with a couple of funny illustrations.
