From the publisher's page:
Only in New York can one battle an Outer God and later, if one lives to tell about it, have a drink in the "speakeasy belt." If you can investigate here, you can investigate anywhere!
The minds behind such Classic Call of Cthulhu® game titles as New Tales of the Miskatonic Valley and More Adventures in Arkham Country are proud to present Tales of the Sleepless City. This is a collection of 1920's era Call of Cthulhu scenarios that could only be set in New York.
