It's that time of the month again - your chance to win a $10 ecard to BN.com, Amazon.com or the book store of your choice (as long as I can send you an ecard).
I'll give you a line or sometimes two from a cozy and you have six days to email me the title and author at firstname.lastname@example.org.
Please DO NOT POST the answer. You can certainly post a comment, but no title or author name in the comments, okay?
Here's the line: "As to what it had all been about, Lieutenant Dubosc was still in the dark, but to him had been delegated the duty of seeing off M. Poirot by the Taurus Express."
Ellery's hint: This book was written by the Queen of Cozies and is a true classic. I love this fastidious detective and his world-famous mustache and the mode of transportation mentioned here should clue you in on the title.
