David Peace’s novel Nineteen Seventy-seven concludes with the hack journalist Jack Whitehead being granted a terrifying apocalyptic vision, seconds before he is trepanned with a Phillips screwdriver by the sinister Reverend Martin Laws. Included in this vision is a curious reference to the wreck of the White Ship, a maritime disaster in 1120 that drowned William Atheling, heir to the English throne, and ultimately doomed England to years of civil war. This article explores Peace’s strange use of the shipwreck in his “Red Riding Quartet,” particularly the way he links it—in the quartet’s final volume, Nineteen Eighty Three—to a revisionist account of the aftermath of the crucifixion that leads a wounded Christ to a tragic death in the cold waters of the English Channel.

Formyl-peptide receptor type 2 (FPR2; also called ALX because it is the receptor for lipoxin A4) sustains a variety of biological responses relevant to the development and control of inflammation, yet the cellular regulation of this G-protein-coupled receptor remains unexplored. Here we report that, in response to peptide agonist activation, FPR2/ALX undergoes β-arrestin-mediated endocytosis followed by rapid recycling to the plasma membrane. We identify a transplantable recycling sequence that is both necessary and sufficient for efficient receptor recycling. Furthermore, removal of this C-terminal recycling sequence alters the endocytic fate of FPR2/ALX and evokes pro-apoptotic effects in response to agonist activation. This study demonstrates the importance of endocytic recycling in the anti-apoptotic properties of FPR2/ALX and identifies the molecular determinant required for modulation of this process fundamental for the control of inflammation.
