Portland author Linda Lee Peterson’s wisecracking crime solver, the indomitable Maggi Fiori, is said to be too smart for her own good.

Thankfully so, as her unbridled curiosity and thirst for adventure offer perfect opportunity for Peterson to unleash her journalist-turned-sleuth on another spine-tingling and dangerous mystery on the streets of San Francisco, “The Devil’s Interval.”

A Stanford alum and author of several works of non-fiction, in addition to her first novel starring Fiori, “Edited to Death,” Peterson will be at Griffin Bay Bookstore to discuss her most recent work Saturday, Nov. 16, at 7 p.m.; co-sponsored by Griffin Bay Bookstore and San Juan Island Library.

Despite a marriage in disrepair, two boys to raise and a magazine to run, Fiori can’t resist plunging into a “whodunnit” where a glamorous socialite is murdered in the backseat of a limo, time is running out on a convicted killer and a mother, doyenne of the San Francisco jazz scene, is desperate to prove her son’s innocence.
