Jay - I don't remember if you specifically recommended Maddie Day's MURDER ON CAPE COD or if I just randomly selected it, but I am enjoying it. My brother and sister-in-law live in New England and spend a lot of time at Cape Cod. My uncle used to go there a lot, too. I've spent a lot of time in New England but I've never been to Cape Cod or anyplace on the New England coast.
My son and both of my brothers love to travel by bike, and bike rentals (Divvy Bikes) were very popular in Chicago, where we used to live. There are bike rental programs here in Eugene, too. I follow another cozy mystery series that involves a bike rental business - Duffy Brown's Cycle Path mysteries. I've read two of them and I think the third one comes out this summer.
I'm not sure if I recommended Maddie Day's MURDER ON CAPE COD specifically either. I just flat out recommend reading all of the books written by Edith Maxwell under her name or the Maddie Day pseudonym. She's just a fantastically entertaining writer in my opinion.
I live just off the Cape but tend to avoid going over the bridge much at all, particularly from late May to mid-September when it is tourist season and the traffic is a disaster at best.
I'm glad you are enjoying the series. And book 2, MURDER AT THE TAFFY SHOP, is even better!
Currently I'm reading Sheila Connolly's ROTTEN TO THE CORE, the 2nd book in her Orchard Mystery series. I bought a cheap used copy off of eBay because I really didn't want to wait for the stores to reopen to read the next book in the series.
