Richard Diamond, Private Detective - The Bill Kirby Murder Case

Richard for was just about to leave his office to return Helen's baby picture, when a nice, older lady stops by his office. She asks "Are you Mr. Diamond?" He says "Yes, but I'm afraid you'll have to come back. I've got to take care of something this morning". She says "Oh, please. I don't know where to go". Richard says "Oh, now wait a minute. Something's really wrong, isn't it? I've got enough time to listen". She says "Oh, thank you". Richard asks "Who recommended me?" She says "My son. Oh, I've heard about you for several years. My name's Mrs. Lenoir Kirby". Richard says "How do you do, Mrs. Kirby? How does your son know me?" Mrs. Kirby says "He doesn't know you well, only by reputation. He was a private detective also". Richard says "Kirby?... Bill Kirby?" She says "Yes". Richard says "Wow. Now, tell me what's worrying you, Mrs. Kirby". She says "Bill  has been acting strangely for the last month or so". He asks "What exactly do you mean by strangely?" She says "Well, he's changed. He's begun to act nervous and irritable. When his sister Gloria or I would try to find out what was wrong, he'd get angry. He got steadily worse. And then one morning, Gloria went into his room. He was asleep, so she started to hang up his trousers. When she turned them upside down, a lot of money dropped on the floor". Richard asks "What do you mean, a lot of money?" Mrs. Kirby says "Well, Gloria said there must have been several thousand dollars, mostly hundred dollar bills". Richard asks "Did he have another source of income?" She says "Oh, no. At least nothing I know of. Gloria, then started to put the money back in Bill's trousers, and he woke up. They had a terrible argument. The next day, Bill packed his clothes, left the house, and got a small apartment, but continued to help with our bills. Three days ago, Bill came over to the house. I could tell he was terribly worried about something. He gave me a package, told me to hide it until he came for it and not to open it. After that, he completely disappeared”.
