Writer George Mann (Dark Souls, Doctor Who, Warhammer 40,000) brings his steampunk mystery novels to comics in a new story for their 10th anniversary, alongside artist Dan Boultwood (It Came!, The Phoenix)! Something foul lurks in London’s sewers, and as skull-faced human bombs are detonated all around the city, Sir Maurice Newbury and Miss Veronica Hobbes are dragged to its stinking heart! Plus: a brand-new Newbury & Hobbes prose short by George Mann, serialized in each issue!
