Synopsis "My Best Friend Has Been Medicating My Husband Without His Knowledge"
The analyzer flags at 2:14 in the morning and Jo almost releases it anyway.Night shift in the core lab is four hundred feet of humming stainless steel and one person. The chemistry line runs itself most of the time. Specimens ride the track, the probe drops, numbers land in the queue, and Jo decides which ones a human being needs to look at before they go into a chart. Most nights it's two hundred eighty tubes and eleven decisions she makes by hand.Tonight, accession 4471-0392 comes up yellow on a trace and mineral profile.Lithium: 0.4 mEq/L.She runs it a second time. She runs it on the backup analyzer. She runs both levels of controls. By 2:47 she has spent thirty-three minutes proving a number she believed the first time.The therapeutic window for lithium starts at 0.6. On a patient who takes lithium, 0.4 is a boring number.On a patient who doesn't take lithium, 0.4 isn't a number at all. It's an event.She pulls the requisition.Patient: ADKINS, ABRAM R.She processed her husband's blood for three hours without knowing whose it was.She ordered this panel eight days ago.

She does not call the police yet. She prints a pharmacy label on her own employer's printer at ten past three in the morning, puts it on a vial of calcium tablets, and places it in the downstairs bathroom cabinet at exactly eighteen millimeters from the front edge and four centimeters left of the hinge.Then she photographs it with a ruler in the frame.She wants to know one thing: whether the woman who has a key to her house looks in her cabinets.At 9:47 the next morning, the vial is three millimeters from the front edge, two centimeters left of the hinge, and turned label-in.She was careful about the wrong element. Her best friend was careful about the right one.What to Expect: Best friend betrayal - lithium in a smoothie, twice a week, for sixteen months Clinical lab scientist protagonist who builds her own evidence chain at three in the morning Evidence trail - an analyzer flag, a dilution calculation, a SpectraCore report, a vial moved eight inches A protagonist who tells the detective the four things she did wrong before she tells him what her friend did No infidelity - nobody touched anybody Power ending - a signed statement, a chain of custody the defense cannot break, and a neurologist who writes the word normal on paper Support character readers will love (Dante, who is adjacent to bleeding and makes her laugh at three in the morning) Standalone - read in any order No cliffhanger One-sitting binge read (28,000 words)Heat Level: Low (emotional intensity, not explicit)Vibes: Clinical, exact, quietly devastatingSeries: My Best Friend's Betrayal, Book 33
