I have never read an Ellery Queen mystery before this one, except for a short story, The Adventure of the Seven Black Cats when I was a teenager. I remember liking it. His novels are not easily available in India nowadays, so when I saw this in a second-hand shop, I immediately picked it up.
Well, I must say that Mr. Queen is different from the other investigators in that he throws a challenge at the readers to solve the mystery themselves, after he has laid all the facts on the table. In this case, I took up the challenge, and came through in flying colours! I rightly deduced the murderer. And instead of feeling letdown, I felt pumped up that I was as smart as the detective!
Well, more about that later. Onward to the story...
In his palatial mansion on Spanish Cape, (which, in the author's words, is "peculiar coastal formation on the Atlantic seaboard", an "out-thrust headland of bare rock... connected with the mainland by a narrow tongue of cliff", which is "utterly private and virtually inaccessible") the millionaire Walter Godfrey has assembled a singularly unlikeable bunch of guests. Of the whole lot, the most despicable is John Marco, a gigolo and a bounder of the first water; who is eminently "murderable", and who does get murdered in classic whodunit tradition. But before that, there are mix-ups galore.
First, David Kummer, Godfrey's brother-in-law (his wife's brother) gets kidnapped by a mentally deficient goon called Captain Kidd, under the mistaken impression that he is John Marco, while he and his niece, Rosa Godfrey, is out on the grounds. Kummer is just advising Rosa to stay away from Marco while this mishap occurs. Kidd ties Rosa up in a lonely cottage and carts Kummer off to the sea in a stolen cruiser. While she is languishing thus, the person who apparently hired Kidd to bump Marco off discovers his/ her mistake and takes remedial action. Marco is discovered, strangled to death on the beach terrace. Except for a hat and a cape, he is stark naked.
And that is when Ellery Queen steps into the picture. Accompanied by his friend Judge Macklin and the rather bone-headed inspector Moley, he succeeds in solving the crime - and pulling the proverbial rabbit out of the hat.
Before continuing further, I must warn you that there are mild spoilers. My explanation might point you on the way to identifying the murderer.
How I solved it: I concentrated on the least likely person to have committed the crime, because that is the standard whodunit tradition; then I scouted around for ways in which that person could be the murderer - and bingo! I found that the most exasperating clue could be perfectly explained in case that was the solution. And I was right! I had got to exactly where Mr. Ellery queen had got.
This is a good mystery, though rather transparent. I don't know whether all the Ellery Queen mysteries are the same. I must try my luck at solving some others!
