Three Witnesses by Rex Stout

Three stories all hinging on the clues provided by one significant witness. In "The Next Witness," a man bribes an answering service to listen in on his wife's phone calls. When one of the women at the service ends up dead, the man is put on trial. It is during the trial that Nero Wolfe (who seldom leaves his home), has an inkling towards the truth and actually joins Archie in the field, interviewing the other women of the answering service.
"When a Man Murders..." features a man who makes it back from the war, only to be murdered in a hotel. Was it the man's wife who has now married another man? She also used her rather large inheritance to purchase her new husband's business though they both claim to be ready to give back the money if only they can stay together. Of course, it could also be the man's aunt or her two children  who mutually inherited the other half of the man's estate.
The last story, "Die Like a Dog" relies on some rather interesting coincidences for Archie to end up with a black lab whose owner has just been murdered.
A fun read and nice to have short stories that are easy to get through.
