A Life of Mysteries

I've spent most of my life reading and collecting mystery novels. This year I've decided to read through my entire collection again. My preference is for the classic English "Golden Age" puzzle mystery, although there are many from other countries and other genres as well. I've purged the collection at times in the past, and there are some good ones I've never gotten to, so there are gaps in it, and that's fine with me. My object in this exercise is to enjoy them all over again.
