Fans have long been curious about the names of Strike’s other two nephews. Troubled Blood finally introduces us to Jack’s brothers: Luke and Adam.

Adam is the youngest of Lucy and Greg’s three sons and, in Strike’s words, he’s a “whiny little prick.” 

During Strike’s time with his family in Cornwall, Adam doesn’t show any particular interest in spending time with Strike, but during an argument with Lucy, she tells him: 

“‘Adam cried when Jack came home from the War Rooms! And then you come down here,” said Lucy, who seemed determined to get everything off her chest now she’d started, “and you only bring a present for Jack. What about Luke and Adam?’”
