This racing, gambling set gets rid of a lot of loose money in notes. There couldn’t be a better way of getting it into circulation.”
“And where do we come in?”
“This way. Young St. Vincent and his wife are friends of yours, I understand? They’re in pretty thick with the Laidlaw set—though not as thick as they were. Through them it will be easy for you to get a footing in the same set in a way that none of our people could attempt. There’s no likelihood of their spotting you. You’ll have an ideal opportunity.”
“What have we got to find out exactly?”
“Where they get the stuff from, if they are passing it.”
“Quite so,” said Tommy. “Major Laidlaw goes out with an empty suitcase. When he returns it is crammed to the bursting point with Treasury notes. How is it done? I sleuth him and find out. Is that the idea?”
“More or less. But don’t neglect the lady, and her father, M. Heroulade. Remember the notes are being passed on both sides of the Channel.”
“My dear Marriot,” exclaimed Tommy reproachfully. “Blunt’s Brilliant Detectives do not know the meaning of the word neglect.”
The Inspector rose.
“Well, good luck to you,” he said, and departed.
“Slush,” said Tuppence enthusiastically.
“Eh?” said Tommy perplexed.
“Counterfeit money,” explained Tuppence. “It is always called Slush. I know I’m right. Oh, Tommy, we have got an Edgar Wallace case. At last we are Busies.”
