I'm really happy to see that Chaosium have fixed this PDF so that it is now truly sublime, gorgeous and without display errors (I originally gave a harsh review which I now humbly and gratefully retract). Since it is mainly grey scaled it will also be more printer-friendly than other ebooks/PDFs.
The gaming content more than lives up to the title (although I recommend that long time Call of Cthulhu fans read the other reviews here regarding exact comparisons to the previous Cthulhu by Gaslight edition).
I particularly like the literary tie-ins with books of the period (including a Martian invasion!) The handouts and maps are perfect as well as the good looking character sheets.
Also Chaosium have now added an uber-useful map of London - which I believe is a "pull-out" in the printed version.
Great job. Very yummy.
Be careful in those dangerous foggy streets...
