My UK mule’s schedule is a bit out of alignment with my desires, so a quick online purchase, and, these two books are in transit .. counting the days. I found them at Amazon.com.
The first book in this series; Corduroy Mansions. (web images) Book two is available as an audio cast by the: London Telegraph, The Dog who came in from the Cold Read by the inimitable Andrew Sachs, best-known for his performance as Manuel in Fawlty Towers. The Telegraph is an excellent on-line newspaper, and I enjoy these ventures into mixed / multi media offerings.
