Take fascinating journeys with this quartet of titles

A roundup of novels new in paperback.

“Two Kinds of Truth” by Michael Connelly (Grand Central Publishing, $9.99). Connelly’s written more than 30 crime-fiction novels — all tight, smart procedurals with intriguing characters. My favorite is Harry Bosch, and this is the 20th Bosch novel. The veteran detective, formerly of the LAPD, now works cold cases for the San Fernando Police Department. (And, presumably, still listens to jazz and breaks rules.)

“Smile” by Roddy Doyle (Penguin, $16). The Booker Prize-winning author’s latest novel is a haunting tale set in contemporary Dublin. “Readers may be sharply divided over where Doyle takes them in the end,” wrote a Seattle Times reviewer, “but none will quickly dismiss this artful meditation on pain, memory, and how we build the stories of our lives. It is his most powerful and sobering novel since ‘The Woman Who Walked into Doors.’ ”

“The Mitford Murders” by Jessica Fellowes (St. Martin’s Press, $16.99). Need a “Downton Abbey” fix while we all wait for the upcoming movie? Fellowes — author of “The World of Downton Abbey” and other books (she’s also the niece of “Downton” creator Julian Fellowes) — kicks off a mystery series set in 1920s London among the famed Mitford sisters.

“Asymmetry” by Lisa Halliday (Simon & Schuster, $16). A national best-seller and winner of the 2017 Whiting Award for fiction, Halliday’s novel at first seems to be the story of a love affair, then becomes something more. “The moment ‘Asymmetry’ reaches its perfect ending,” wrote a Washington Post reviewer, “it’s all the reader can do to return to the beginning in awe, to discover how Halliday upturned the story again and again.”
