"Well, you see, sir, London is so full. There is too much rushing about for calm, steady work. In such a task as ours a man wants a double set of eyes this week. Suppose my lady takes it into her head to go to the Derby? It will be all a job not to lose sight of her."
"What lady do you refer to?"
"Ida White, to be sure. She's a bit of a blood, sir, and the result of the Derby may mean a lot to her."
"Does she bet, then?"
"There is not much doubt of that, sir."
"How did you discover it?"
"Oh, easily enough. We have ways of our own. Why, sir, when I found out last night where she lives, what did I do an hour afterwards but present myself to the landlady of the house and ask her whether she could let me have a room for a week or two? I didn't tell you that there was a bill in her window, 'A Bedroom to Let to a Single Young Man.' Well, if I ain't a single young man, what is that to do with anybody--except my wife? I'm a soft-spoken chap when I like, and before the landlady and me are together five minutes I'm hand-and-glove with, her, and already a bit of a favorite. So I take her room and sleep there last night, and the first thing this morning down-stairs I am at the street door when the postman comes with the letters. Well, sir, would you believe it, he delivers five letters, and every one of them for Miss Ida White? I, opening the door for the postman, take the letters from him, and hand them one by one to the landlady, who comes puffing and panting up from the basement she weighs fourteen stone if she weighs an ounce. 'Miss Ida White,' says I, giving her the first letter. 'Miss Ida White,' says I, giving her the second letter. 'Miss Ida White,' says I, giving her the other three, one by one. 'Why, it is quite a correspondence!' All these letters are from Boulogne, sir, from betting firms. I know them by their outsides; I believe I should know them by the smell. Then, sir, there's something else. My lady is fond of newspapers. What kind of newspapers? Why, the sporting ones, to be sure. The Sportsman, Sporting Life, Sporting Times, Referee, and the like. Put this and that together, and what do you make of it, sir?"
"You are progressing, Fowler," I said.
"Yes, sir, we're moving. The landlady, bless her heart, she doesn't suspect what the letters from Boulogne are, but in less than a brace of shakes I worm out of her that Miss Ida White has received any number of them since she came to live in the house."
"Have you an idea what horse she has backed?"
