From the Publisher:
Three witnesses hold all the clues in three crimes of passion, and even Nero Wolfe is left guessing to the very end. A dead millionaire suddenly comes back to life -- only to end up dead again. Did he write his own death warrant years before? Will the black Labrador retriever who follows Archie home prove that man's best friend is a killer's worst enemy? And finally, what do you do when a telephone answering service has three very untalkative operators? The great detective may himself be the witness who will save an innocent man from the chair.
