The Spider's Web

I have always loved Dame Agatha Christie and it was a pleasure to watch this "spider's web" ,which was first a play (later novelized by Charles Osborne)

It's impossible to mention this play in the same breath as her stage masterpieces ("witness for the prosecution" and "the mousetrap") because the ending is not as mind-boggling as the poster reads ,but for a Christie buff ,it's still good value : the red herrings are present ,(black) humor too -we're sometimes closer to a comedy -,and the whole cast is up to scratch ;the dead body which appears and disappears may remind you of HItchcock's "trouble with Harry".
