The Fuller Memorandum

The third book in the Laundry Files series is rather darker, and perhaps also somewhat more complex than the previous books in the series. With a group of cultists as the main enemy this time round, the connections with the Cthulhu Mythos are, if anything, more explicit than before. This, however, is a very modern updating of Lovecraft with some horrific scenes that HPL would likely have shied away from. The humour of the previous two books is still here, although most definitely subdued when it comes to the final climax.

It's more obviously horror than, in particular, the Jennifer Morgue, and has all the more impact for it. The plot itself also reveals rather more about the Laundry, and, in particular, Angleton, whose disappearance forms a major plot thread. All in all, a worthwhile addition to the series.
