Donald J. Sobol, the US author best known for the Encyclopedia Brown mystery series, has died at the age of 87.
Having fought in the Second World War, Sobol worked in the New York newspaper business before starting to write the syndicated Two-Minute Mysteries series in 1959. Relating the adventures of criminologist Dr. Haledjian, the stories were popular and encouraged Sobol to begin writing the Encyclopedia Brown series in 1963.
Altogether, Sobol wrote more than 60 books. The Encyclopedia Brown series has endured and remains in print today via Penguin, with the most recent edition, Encyclopedia Brown and the Case of the Carnvial Crime, having been released in 2011.
