Map piece
One of the clues to the Murder of Augustus Darcy is a map of London marked with mysterious symbols and lines. The map has been cut into sections and circles have been cut out of the various sections. At the centre of the circles is a tube station and on each circle is a mysterious symbol.
Two types of circle have been discovered so far. One type bears a phrase from The Enochian Calls used by Dr Dee and later Aleister Crowley (who appears in the Liber Fumo. These are a sequence of angelic summonings which refer to cataclysms and a day of judgement. The others bear the name of an Aethyr, angelic presences mentioned in much of Crowley's writing and particularly Liber 418. The list of each Call and Aethyr is below, there are 18 Calls or Keys and 30 Aethyr.
As yet there no connections has been determined between the Aethyr and the stations they sit upon or the Aethyr and the Calls to which they are connected. It seems likely that the Aethyr represent gates or sites of power which the different calls will awaken. Considering the apocalyptic nature of the Calls it would seem that someone of some group is attempting to awaken a significant power beneath London. This is probably linked to the Prophecies of Merlin mentioned in the Liber Fumo and seemingly connected to the magical war that is hinted at in the entries. This is currently speculation based on hints in the Liber and the text of the Calls. More of the map may be neccessary to determine the nature of the connections between stations, Aethyr and Calls. The idea of a mystical power linked across London by its buildings and locations is not a new one. After the Great Fire the naturalist, bibliophile, Royalist and scientist Sir John Evelyn offered a plan for the rebuilding of London which was based on the Kabbalah. This plan is mentioned on the very first pages of Darcy's Guide and may well have inspired the magical plot.
At this moment there is one other piece which is not a circle but is still part of the overall pattern. This part shows the City of London.

Polygonal Cutout
In addition to the circular map cutouts, one example has been discovered to date of a polygonal cutout which shows a larger map segment overlaid with circles apparently representing the Kabbalistic "Tree of Life"
Reconstruction Attempts
Although many of the cutout sections located to-date fall outside the boundaries of the three known map sections, an attempt has been made to construct a digital composite which reunites the map sections and the cutout sections within them.
A more speculative attempt at placing all currently known elements into a single map.
