Capitalizing on the fun of her first book, Tara Lazar returns to the Al F. Bet detective agency for another caper. It seems Question Mark was all bent our of shape because all the uppercase letters in Capital City has gone missing and to emphasize his point, he had brought along Exclamation. Would Private I take the case? if he didn't solve this one, with all the capital letters gone, there would be incomplete sentences dangling everywhere. What results, as Private I tries to solve the case, is a punny introduction to punctuation when he tries to interview them. They are all too busy to talk, only the Quotation Twins are willing to talk: "Yeah, something's definitely up, besides us...But don't quote us on that." This is written with the same kind of hard-boiled film noir mystery way of speaking and illustrations as 7 Ate 9. Once again, I found it did not work with my younger readers who are 4-5 years-old, but it did work better with kids 6+. My favorite part was the appearance of the Grammar Police represented by Elements of Style and the Chicago Manual of Style.
