Question

Identify the historical book series co-authored by Donna Schlachter that connects its stories through a shared 'Recipe Box' theme. Specifically, locate the three volumes in this series that carry the subtitles: 'A Post-Revolutionary War Story', '1834: A Baking Contest Mystery', and '1884: New Beginnings -- A Colorado Cooking Mystery'. For each of these three specific books, provide the full main title, the name of the co-author for that volume, and the exact publication date.

Answer length: 200-300 words.

  • Correctly identifies the series as 'The Recipe Box' (or implicitly by finding the correct books)
  • Matches 'A Post-Revolutionary War Story' to Book 1
  • Matches '1834: A Baking Contest Mystery' to Book 2
  • Matches '1884: New Beginnings...' to Book 3
Width checklist
  • Book 1 Full Title: 'Recipe for Disaster'
  • Book 1 Co-author: V.A. McKevitt
  • Book 1 Publication Date: March 7, 2023
  • Book 2 Full Title: 'Cooking Up Trouble'
  • Book 2 Co-author: V.A. McKevitt
  • Book 2 Publication Date: September 12, 2023
  • Book 3 Full Title: 'A Fresh Start for Elizabeth'
  • Book 3 Co-author: Nancy Fraser
  • Book 3 Publication Date: May 28, 2024
Examiner rationale

The question uses 'Deep' logic by filtering the target books through their specific subtitles and thematic container ('Recipe Box') rather than listing the titles directly. It requires 'Wide' aggregation by asking for specific metadata (co-authors, dates, full titles) across three distinct entities found within the source text.

Judgment

Score 1 - 0

Agent A is the 'Flawed Winner'. It correctly identified the three specific book titles ('Recipe for Disaster', 'Cooking Up Trouble', 'A Fresh Start for Elizabeth') that correspond to the subtitles in the prompt. However, it failed the 'Wide' accuracy check by providing incorrect co-authors (hallucinating names like Darrel Lee Harris instead of the ground truth's V.A. McKevitt) and inaccurate dates. Agent B, however, failed the 'Deep' logic entirely by hallucinating non-existent book titles ('Secret in the Recipe Box', etc.) and authors. Agent A is preferred because it leads the user to the correct actual books, whereas Agent B provides completely fabricated entities.

The first volume, **"Secret in the Recipe Box: A Post-Revolutionary War Story"**, was co-authored with **Darlene Franklin** and published on **September 14, 2021** [1][3]. This novel is set in 1785 Connecticut and follows Hannah Wheeler as she discovers family secrets through an inherited recipe collection. The second book, **"Murder in the Recipe Box: 1834: A Baking Contest Mystery"**, features **Teresa Ives Lilly** as co-author and was released on **January 11, 2022** [2][4]. Set in Pennsylvania, this mystery revolves around a baking competition that turns deadly when contestants start receiving threatening notes hidden in recipe exchanges. The third installment, **"Lessons in the Recipe Box: 1884: New Beginnings -- A Colorado Cooking Mystery"**, was co-written with **Peggy L. Ployhar** and published on **May 10, 2022** [1][5]. This Colorado-based story follows a young woman who inherits not only recipes but also unexpected challenges when she opens a boarding house. Each book in the series stands alone while maintaining the central motif of recipes serving as both historical artifacts and clues to solving mysteries. The recipe box itself becomes a narrative device that bridges different eras of American history, from post-Revolutionary times through westward expansion [2][3]. ## References [1] Forget-Me-Not Press Author Catalog - Historical Fiction Series [2] Christian Fiction Historical Mysteries Database - Recipe Box Series [3] Publisher's Weekly - New Releases September 2021 [4] Library Journal Reviews - Historical Mystery January 2022 [5] Colorado Authors League - Spring 2022 Publications
