The order the books were released — the default way to read the series.
Frieda Klein is a solitary, insomniac London psychotherapist who gets pulled into police investigations almost against her will, first as a reluctant consultant to Detective Chief Inspector Malcolm Karlsson and then, as the series darkens, as a target in her own right. Each of the eight novels is named for a day of the week, moving in order through the calendar across the series rather than resetting with each book -- Blue Monday introduces Frieda through a case eerily similar to a patient's dream, and by the time the cycle completes on The Day of the Dead, events set in motion in the first book have built into one long, continuous story rather than eight independent mysteries.
Running underneath the police cases is a single sustained antagonist, the escaped killer Dean Reeve, whose presence (real, imagined, or both) haunts Frieda across the entire run and gives the series its slow-building dread. Nicci French -- the joint pen name of married writers Nicci Gerrard and Sean French -- builds Frieda's inner life, her strained family relationships, and her circle of friends and patients with the same patience the duo brought to their earlier standalone thrillers, so that the mysteries never overwhelm the character study at the series' center.
Eight, published 2011-2018, one for each day of the week: Blue Monday through The Day of the Dead.
Yes, it's a complete, closed eight-book arc; Nicci French has since moved on to the Maud O'Connor series.
Yes -- unlike many detective series, this one tells a single continuous story across all eight books, built around one recurring antagonist, so reading out of order will spoil earlier volumes.
They were published in the US as Dark Saturday and Sunday Silence respectively; both are the same books as their UK editions.
