One game I have enjoyed over the years is the Call of Cthulhu, partly because it is a game of investigation but mainly the era of the roaring 20s.  It even made number  in my top ten game list.

Over the years Chaosium have released numerous adventures and globe trotting campaigns including the spectacular Masks of Nyarlathotep. The adventure is very well written with all the important clues indexed and referenced for ease of play by the busy GM, the only downside is that there appears to be material missing; perhaps things man was not meant to know that didn’t make the cut.

A number of years ago, I saw that there was going to be a companion written for this game and released as one of the Monograph line that Chaosium were printing; for one reason or another it never appeared until the unfinished edition was released over at the Yog-Sothoth forums.  Now they plan on finally polishing the document and releasing it to the general public (no relation 🙂 ) .
