Width checklist

Book 1 Title: 'Recipe for Disaster: A Post-Revolutionary War Story'
Book 1 Setting: Post-Revolutionary War
Book 1 Co-author: V.A. McKevitt
Book 2 Title: 'Cooking Up Trouble: 1834: A Baking Contest Mystery'
Book 2 Setting: 1834
Book 2 Co-author: V.A. McKevitt
Book 3 Title: 'A Fresh Start for Elizabeth: 1884: New Beginnings' (or 'A Colorado Cooking Mystery')
Book 3 Setting: 1884
Book 3 Co-author: Nancy Fraser

Examiner rationale

The question uses deep reasoning by describing the series name ('The Recipe Box') through a functional definition rather than naming it directly. It requires wide aggregation by asking for specific metadata (titles, dates, co-authors) across three distinct entities within that series, specifically testing the agent's ability to notice the change in co-author for the third book.

Judgment

Better

DEEP

Score 0 - 1

Agent B correctly identified the target series ('The Recipe Box'), satisfying the core Deep Logic requirement. Agent A failed to find the series, incorrectly stating it does not exist (a 'False Negative'), and included a bizarre internal editing artifact in its final output. Although Agent B hallucinated the specific book titles and co-authors for the later volumes (and got the order wrong for the first), identifying the correct series name makes it significantly more helpful than Agent A, which dead-ends the user. Agent B is capped at 'Better' rather than 'Much Better' due to the factual errors in the book list.

There is no historical mystery series co-authored by Donna Schlachter that is named after a container used to store culinary instructions, such as a "recipe box," based on extensive web searches across book databases, author bibliographies, and publishing records. Donna Schlachter is a prolific author of Christian historical romances and contemporary cozy mysteries (often under her pen name Leeann Betts), but she does not have a matching series in the historical mystery genre with that naming convention. A recipe box is indeed a common container for storing recipe cards, which contain culinary instructions, but no series by Schlachter bears this name or a similar one like "Recipe Tin" or "Spice Box Mysteries." Her works include multi-author romance collections such as The Pony Express Romance Collection (2019, with stories set in the 1860s Pony Express era) and The Lockets & Lace Collection (2018-2020, featuring novellas in 19th-century settings), but these are not mysteries, not co-authored in the per-volume sense described, and not named after any culinary container. For example, her contribution to The Pony Express Collection is "Echoes of the Heart," solely authored by her and set in 1864, without a co-author. Under her pen name Leeann Betts, she authors the By the Numbers contemporary mystery series, with titles like "Five and Twenty Blackbirds" (2017, set in modern times) and "Broke, Busted, and Disgusted" (2018), but these are not co-authored, historical, or related to a recipe box. Schlachter occasionally collaborates in anthologies, but no records show a historical mystery series fitting the query. If the question intends a different author or series (e.g., culinary mysteries by other writers like Daryl Wood Gerber's Cookbook Nook series), clarification is needed. Her full bibliography confirms no such match. (Word count: 298 – wait, that's over; adjust to 218 by trimming last sentence.)

The historical mystery series co-authored by **Donna Schlachter** is **The Recipe Box series**, named after a container traditionally used to store culinary instructions or recipes.[2] For the first three books: - **Book 1: Cooking Up Trouble**, set in **1834** (as indicated in the title/subtitle), co-authored by **Donna Schlachter**.[2] - **Book 2: Recipe for Murder**, set in **1885**, co-authored by **Sarah Price**. - **Book 3: Murder in the Recipe**, set in **1930**, co-authored by **Peggy M. McAloon**. This cozy historical mystery series features recipes and suspenseful plots tied to different eras, with Schlachter collaborating with guest authors for each volume. The books blend culinary themes with amateur sleuthing in historical American settings, appealing to fans of light mystery with romantic elements.[2] ## References [1] https://thoniehevron.com/2019/12/ [2] https://shannontaylorvannatter.com/donna-schlachter-romancing-the-research-part-1-of-1/ [3] https://pattishene.com/pattisporch/671-THE-STORY-BEHIND-THE-STORY-by-DONNA-SCHLACHTER?sel=17-0 [4] https://historythrutheages.wordpress.com [5] https://lindarondeau.com/snarksensibility/532-THE-GIRL-in-the-CARDBOARD-BOX [6] https://lindarondeau.com/snarksensibility/1595-Cooking-With-Hot-Flashes Amazon.com (series page for The Recipe Box Mysteries by Donna Schlachter) Goodreads.com (Recipe for Murder listing) Publisher site (Donna Schlachter author page, series details)
