As a key forerunner of the “British invasion” that helped reinvigorate comics in the late ‘80s and early ‘90s, it’s no surprise that much of writer Peter Milligan’s best work sprang from or was grandfathered into the Vertigo imprint of DC Comics, for many years the destination for literary, challenging mature-readers comic storytelling. Milligan, who in recent years has flourished everywhere from Dynamite (Terminal Hero) to Image Comics (The Discipline) is back this week with Britannia, a prestige-format Valiant mini-series with artist Juan Jose Ryp. Set on the outskirts of the Roman Empire in 65 A.D., Britannia follows “the world’s first detective” as he pursues an unholy mystery. To coincide with his latest debut issue, Paste counted down ten of the scribe’s best comics to hit American shelves (as much of his shorter British work never made it stateside, we narrowed the list to titles easily available on this side of the pond). Let us know on Facebook or Twitter if your favorite Milligan outing didn’t make the cut (sorry, Skin fans).
