The John Tyler series opens with Anthrax Island, in which nine people are trapped on a government-controlled, anthrax-contaminated island off the coast of Scotland after the only person who can fix their decontamination chamber turns up dead. It’s a locked-room thriller in an outdoor setting, and it sets the template for the rest of the series.
Black Run moves Tyler to a ski resort in the Alps for an abduction mission that goes sideways, landing him on a rusting cargo ship crewed by smugglers and mercenaries. The final book, 77 North, takes the action from central Africa to London to the frozen Arctic. Each book works as a standalone thriller while building on Tyler’s character across the trilogy.
