Cosmo

Born to the life and leisure of British aristocracy, the man to be known as Cosmo rose to prominence as a gentlemen detective. A master thespian and master of disguise, he traveled the world engaging in several seemingly inexplicable mysteries during the 1930s.

In his first recorded adventure, Cosmo matched wits with an enemy agent named Taro, who was every bit the sleuth and master of disguise that Cosmo was. Shortly thereafter, he traveled to Capetown, South Africa to investigate a diamond smuggling operation. He then went on to solve the murder of his musician mentor, Emil Rogello. Less than a year later, Cosmo traveled to the United States where he became involved in a scandal at the Russian Legation in New York City, and even shared in a cowboy-style adventure in Texas.

"The Rhangwa Pearls"
Early March 1937 gem-collector Gregory Dillingwater gained possession of the Rhangwa pearls, a priceless bunch of gems. Later on, he received a note that said that the pearls would be stolen from him on the week of the 15th. It is signed by "Taro", a well known thief. After being alerted, police captain Burke decided to call Cosmo to help with the case. Cosmo came up with a plan and explained it to Dillingwater.

Meanwhile, Taro had easily slipped past the police, and overcame Dillingwater's butler, Buckley. Now disguised in a butler’s suit, Taro attempted to poison Dillingwater by putting a pellet in his drink. Instead, Cosmo disguised as Dillingwater lunged at Taro and knocked him to the floor. After the police placed Taro under arrest, the Rhangwa pearls remained safe in Dillingwater's collection.
