His assignment leads him to a splendid but terrified harem of veiled beauties, a millionaire sultan with a roving eye, and a gang of turbaned mystery men with a lust for violence. Corrigan's protect a priceless ruby as red as the color of murder.
Always good to read a classic mystery. I don't think I've read any Ellery Queen before. This was published in 1966, so a few references were dated (lack of cell phones and computers, a few phrases) - but overall it stood the test of time as a classic mystery.
