The highest-rated mystery on the list is, of all things, a wedding episode. Norman and Rita's long-delayed big day finally arrives, and right on cue a letter surfaces carrying clues about a young woman's missing mother. So the Signed, Sealed, Delivered crew works the case between fittings and vows. Eric Mabius and Kristin Booth anchor it, and the guest list includes Carol Burnett and Barry Bostwick, which tells you the tone. This is the warmest kind of sleuthing, all heart and old correspondence, and at 8.2 the fans plainly agree. Cozy.

A strange package turns up in a prop mailbox on a commercial set, and inside is what appears to be someone's bucket list. The postal detectives set out to find who it belongs to, a search that drags them all the way to Las Vegas, New Mexico. Meanwhile a father-son backpacking trip goes badly wrong. Eric Mabius and the team treat lost mail like a calling, and this one leans hard into the show's whole faith-and-providence streak. Rated 8, with a search-and-rescue twist I didn't see coming. Cozy, with a lump-in-the-throat finish.

This is one of the darker corners of the list, so consider yourself warned. A serial killer escapes custody, someone takes a shot at Detective Travis Burke, and a house explosion uncovers a mummified body inside a wall. Literature professor Amy Winslow (Jill Wagner) and Travis (Kristoffer Polaha) team up with his FBI ex to find the thread tying it all together. Rated 7.4. Mystery 101 at its most thriller-adjacent, and it ends on a genuine cliffhanger. More tense than cozy.

The POstables pile into an old Winnebago and head across Colorado, hunting for a small boy they fear may have been kidnapped. Their only map is a wonderfully unlikely one: a 1980s instant camera and the strange photographs it spat out. Eric Mabius and Kristin Booth lead, with Jamie-Lynn Sigler guesting. Rated 7.4. It's a breezier, more scenic detective story than the usual office-bound cases, and the road-trip framing suits the team. Cozy, no real menace.

Tom Selleck's Jesse Stone takes an unpaid consultant gig to dig into a cold case: a woman believed to be the fourth victim of the Boston Ripper, even though the killer insists he only took three. Back in Paradise, Jesse keeps a worried eye on a wayward teen. Rated 7.3 over more than 4,000 votes. This is the grown-up end of the Hallmark mystery spectrum, moody, slow, and genuinely noir. Not cozy in the slightest. Save it for a quiet, serious night.

Professor Amy Winslow heads to Seattle to give a talk on mystery fiction and crosses paths with a tech mogul launching a crime-solving AI, who promptly turns up dead. Jill Wagner and Kristoffer Polaha trace his death to another killing and a web of blackmail that reaches into Travis's own past. Rated 7.3. Sharper and a shade darker than the cozier Mystery 101 entries, with a genuinely clever puzzle underneath. Mid-cozy, leaning serious.

The case plays out at the Kent Lake Lodge in Ithaca and turns personal fast, pulling in family business and old sibling tensions. Rated 7.3.

Mid-cozy, light on violence and heavy on red herrings.

Then art imitates life when one of the actors is killed for real. Rated 7. The play-within-the-investigation framing is a great hook, a scripted murder that goes horribly off-script. A change of scenery for the Real Murders Club. Cozy, with a theatrical wink.

Cozy, bloodless, and catnip if you read a lot of whodunits.

Cozy, with cookies, naturally.
