Just a Corpse at Twilight (Grijpstra and de Gier Series #12)

Retired Amsterdam policeman Grijpstra receives a frantic late-night phone call from his old partner, de Gier—now living on an island near Jameson, Maine—who fears he may have accidentally killed his girlfriend. He is being blackmailed and can’t remember if he did it; he was just too drunk. Would his old partner please fly over at once? Grijpstra grudgingly makes his way to the US to help his old partner and confronts his own demons along the way.
