""A"" bookstore in Toronto? Not a specialist bookstore, likely to carry rare and obscure children's books? Well, there you are. As the the shipment never arriving, it's usually a matter of incompetence rather than conspiracy. I have two words for you, Mr. Paterson: amazon.com (two words and a dot). Thanks for trying. It sickens one a bit to think how many people may have looked for the book, after the two copies suggested by the publisher and ordered by the shop were already sold. (The name of the Toronto bookshop likely to have my stuff escapes me, but I believe it still exists, and might be fun to visit).
