Bulldog Martin is another series with a largely unexplained, characterless hero, though the art is decent, and the stories are not bad. The biggest drawback is his sidekick, a short overweight black man named Jonah, who exists solely for comic relief.
After stumbling across hoods who drug and kill horses to fix races, Bulldog heads over to England to check out Lord Frawley’s famous airport (that’s what they call it.) He discovers Frawley is really working with foreign agents, using his runway to smuggle information and people in and out of England, and causes Frawley’s plane to crash, killing him.
Then it’s off to Algiers, where he and Jonah are attacked on the street by slavers, and wind up rescuing American heiress Sybil Lane from their clutches. In his next story, Bulldog is in Egypt with Sybil’s explorer uncle, and captures the Phantom, the leader of a gang of tomb robbers.
Bulldog and Jonah then go climbing in the Swiss Alps, and catch some gold thieves whose plane came down in the moutains.
So from what we call, Bulldog is not a policeman or a private detective or anything, just a guy who keeps being in the right place at the right time.
Bulldog Martin continues in the Early Golden Age, and hopefully gets a bit more depth to it.
