Sahara Desert
Sahara Desert (or Desert of Sahara) was a desert region of northern Africa. 

In The Big Good-Bye, Paddy Fallon, a friend of Detective Jim Tierney, asked him if he considered moving to a more lively place than the Northern Valley where his saved money could work for him. Perhaps, according to Fallon, Tierney could set up shop selling fishing tackle in the Sahara Desert. ()
