THE CASE OF THE MARMALADE CAT. REVIEW BY JAMES, GRADE 4, MR. PRICE’S CLASS, MIDDLEBURY PUBLIC SCHOOL, ONTARIO. The Case of the Marmalade Cat starts off with Clarice, a girl who likes detectives and wants to be one to. Clarice told her friend Sadie and then she wants to be in the agency too. On their second day in business a boy named Brick wants to join and he convinced them that he would be a good detective and so then he became the third and final detective in the agency. Now they only needed to get a case. Then it happened in the mail-box was a letter. They were to find a missing cat for Miss Parsnip. Strange things go on during the case. Sadie thinks Miss Parsnip is a witch. Brick can walk on fences and talk in cat language. This book takes you too many different places and strange ones too. I didn’t really like that I could guess what was going to happen before it happened. If you like mysteries this is a good book to read.
THE TRAIL OF THE CHOCOLATE THIEF. REVIEW BY CAROL, A STUDENT AT WILLIAMS BRIDGE ELEMENTARY IN RICHMOND, BC PUBLISHED ON THE BC LIBRARY ASSOCATION WEB SITE. Clarice O’Brien is the chief detective. She and her friends Sadie Stewart and Brick (Leopold) Chumley-Smith are on the trail of a Robin Hood chocolate lover thief. Lots of kids lost their toys and all the kids live on False Creek but only one lives in Fairview…I liked the part when Clarice always say, “That is my hunch.” I also like it when Clarice is impressed with the detectives, she sounds so serious.
THE TRAIL OF THE CHOCOLATE THIEF. REVIEW BY DAVE JENKINSON IN CM MAGAZINE (May/June 1994, Grades 3-5, Ages 8-10). …While The Trail of the Chocolate Thief can stand alone, readers familiar with The Case of the Mamalade Cat, might better understand the relationships among the characters, especially Number Two’s sarcastic comments directed at the Chief, and will more fully appreciate the children’s run-in with Dolly Varden and her cat Ginger. A good, readable introduction to more sophisticated juvenile mysteries.
THE MYSTERY OF THE GOLD RING. REVIEW BY IAN MCLAREN IN CM MAGAZINE (September 15, 1995, Grades 4-7, Ages 8 – 11.) …In this episode, the three sleuths (all around twelve or thirteen years of age) are on holiday in Greece with Sadie’s parents. During their stay, a priceless ring is stolen from a local museum. The evidence seems to point to one of the kids from a Canadian school band who are also staying at the hotel. …Heneghan makes no bones about this being a Canadian story. Many references are made to sites in the Vancouver area (where Heneghan lives) and the main reason the children want to solve this case is to preserve the honour of Canadians everywhere. If you want your kids to read Canadian content, look no further. Heneghan also manages to weave a fair amount of Greek history, geography, and mythology into this novel… Without realizing it, the reader could end up learning something. The Mystery of the Gold Ring is a very readable, well-narrated pre-teen mystery. Copyright © 1998 the Manitoba Library Association.
