I love Philo Vance and have read all these mysteries, some of them three times. I still remember how happy I was when THE CASINO MURDER CASE, the last mystery I hadn't found, turned up in paperback briefly, and I bought it. I love that the mysteries are always a murder case with a six-letter name, like GARDEN, or BISHOP or GREENE. (The author had to change the pattern for GRACIE ALLEN, complete with movie tie-in, but he went right back to it.)
