This is Green’s most recent novel of the Nightside, a hidden part of London populated by creatures who never see the light of day. John Taylor is a Nightside PI who specializes in finding things. But something has just found him: Excalibur, the sword of King Arthur himself. Since the sword is practically sentient and turns up only when there’s a big job to be done, what does it want with Taylor?
Private Eye John Taylor is the only thing standing between his not-quite-human mother and the destruction of the magical realm within London known as the Nightside.
In the wake of the war that left the Nightside leaderless, Jeremiah Griffin-one of the last of the immortal human families-plans to fill the power vacuum. But his granddaughter has disappeared, and he wants John Taylor to use his special abilities to find her. Except someone-or something-is blocking Taylor's abilities.
John Taylor has another one of those days, beginning with a showdown at the defunct Nightside carnival between the Voodoo Apostate, the gods he tried to dominate, and Taylor. Next, a call from the editor of the Unnatural Enquirer asking Taylor to find a man who disappeared en route to deliver an afterlife recording he had just sold the rights to. Teamed with a half-succubus demon-girl reporter, Taylor visits the Nightside’s key players and politics as people jockey to replace the recently destroyed authorities. Meanwhile, some heavy-duty characters also seek the recording. More fast, fun, adventurous detection in a setting in which nearly anything’s possible.
There's a new sheriff in town, and he's got the Nightside's rich and powerful quaking in their boots. He's The Walking Man, and it's his mission to exorcise sinners-with extreme prejudice. Problem is, the Nightside was built on sin and corruption, and The Walking Man makes no distinction between evildoers and those simply indulging themselves. He'll leave the place a wasteland unless someone stops him, and P.I. John Taylor has been handed the job. No known magic or science can affect The Walking Man, and if John can't discover his weakness, he'll be facing the very Wrath of God...
