threatened to get private detectives on the job and said everybody was going to have to take a lie-detector test."
    "I take it he hasn't won any popularity contests with the help," Mason said.
    "Not recently," Ellen Robb said dryly.
    "And somebody has been knocking down on him?" Mason asked.
    "He seems to think so, and I would assume he probably is right."
    "Could that person or those persons have tampered with your cash register?"
    She shook her head. "Most of the knocking down that is done," she said, "is done at the bar. People who buy drinks at the bar pay cash, and if the bar is very busy and the bartender takes in four or five payments at once, he can ring up varying amounts in the cash register and there is no one to check on him. For instance, let us suppose one man has a cocktail which is seventy-five cents or a dollar. Another man has a drink which is sixty cents. Another person has bought drinks for three or four, and his bill is two dollars and eighty-five cents.
    "By timing things just right a good bartender can be preoccupied at just the right moment so that every glass gets empty at about the same time. That makes for a rush of business and a lot of payments being made all at once.
    "So then the bartender picks up all the money, goes over to the cash register and starts ringing up sales of varying amounts.
    "If the bartender is good at mental arithmetic, he can add up the figures in his mind and ring up an amount that is exactly two dollars short of the real amount. Then he gives each customer his exact change. Various amounts have been leaping into sight on the cash register, staying there for just a moment only to be superseded by another amount. Nobody can tell for certain what check is being rung up. If the bartender sees someone paying attention to the cash register, he is scrupulously accurate in ringing up the amounts, but if people are talking and not paying too much attention, he'll knock down a couple of dollars and no one is any the wiser. He'll do that perhaps ten to twenty times in an evening."
    "Were you doing any of this work at the bar?"
    "Not last night. I was handling the main cash register. I had the only key to it while I was on duty-at least, it was supposed to be the only key. I would Sit there on the stool, and people would come to me with their checks, or the waitresses would come to check out the amounts due at their tables. I'd take in the money and give out the change."
    "Was there any reason why you couldn't have knocked down if you had wanted to?" Mason asked.
    "There's more of a check on the main cash register. The waitresses issue dinner checks and keep a carbon copy which has to be filed when they go off shift. Theoretically the cash rcgister should show a total income equal to the exact total amount of checks issued by the waitresses. But there are lots of ways of beating that game."
    "How?" Mason asked.
    "Walks, for one."
    "Walks?" Mason asked.
    "A customer pays his bill directly at the cash register," she said. "The amount of the bill is two dollars and eighty-five cents. He gives you a twenty-dollar bill. You pretend to be very much interested in the addition on the check, then apparently something goes wrong with the key on the cash register. You concentrate on that. Eventually you ring up two dollars and eightyfive cents; still without apparently paying too much attention to him, you hand him fifteen cents, then give him two one-dollar bills, then hand him a five, then look back at the cash register for a minute. Nine times out of ten the man will pocket the change and walk away. If he starts to pocket the change and then stops suddenly, or if he still waits there, you take out two additional fives and give it to him with a smile, then start looking back at the cash register again."
    "You seem to know all the tricks," Mason said thoughtfully.
    "I've heard some of them," she said.
    "And you sing?"
    "Yes."
    "Let's hear," Mason said.
    She tilted back her head, sang a few bars
