First read shortly after publication, I vaguely remember being disappointed that there was so little Dirk Gently there. Upon rereading, I have the same disappointment.

Contains some nice bits and bobs published elsewhere, from reviews to anecdotes, and 10 chapters of what would likely have coalesced into a third Dirk Gently novel. Like earlier installments, it starts as individual unrelated fragments, unlike those, we never get to see the whole.
