In the world of detective novels, there's big news this summer — Spenser is back.

Though fans lamented the death in 2010 of Spenser's creator, Robert B. Parker, they have given rousing support to Ace Atkins, handpicked by Parker's estate to continue the character. The new Spenser book Lullaby ($26.95; ebook $12.99) is a gritty, tightly plotted puzzler that hit the New York Times best-seller list the first week it was out.

But don't stop with Spenser. If you are a fan of the genre — whether it be the literary thriller or the hardboiled procedural — here are four more great detectives you should get to know.

Detective: Kinsey Millhone
Author: Sue Grafton

The California private eye has been solving crimes over the course of 22 novels now, beginning with A Is for Alibi in 1982 and continuing through most of the alphabet. In the latest, V Is for Vengeance ($27.95; ebook $14.99), Millhone gets roped into a case while shopping for underwear bargains at Nordstrom. This type of development happens often to Millhone: Her everyday life will intersect with a crime in some way, and then she's off and running. Millhone's charm comes from her unaffected ordinariness: She's a bit of a loner, but she's devoted to her friends; she's smart, but she knows how to learn from experience; and she eats peanut-butter-and-pickle sandwiches. Jump into any of these "alphabet books" and you'll quickly fall under her spell.

Detective: Sir Thomas Lynley
Author: Elizabeth George

George's detective inspector is actually Lord Asherton, a highly educated man of privilege, who is partnered with Detective Sergeant Barbara Havers, a disheveled mess of a woman from a working-class background. George, an Ohio-born American, has given her Scotland Yard officers a respectful if occasionally rocky professional partnership and very separate lives (though Lynley's is the more interesting). George's first Lynley novel, A Great Deliverance, won her acclaim when it was published in 1988, and after 17 books she's no less on her game with her latest, Believing the Lie ($28.95; ebook $14.99). The world that Lynley inhabits is complicated, yes, but George supplies enough background in each book to let us jump into the series anywhere. The intricate plots always take center stage anyway.
