“Are you quite all right, sir?”

The answer came in a lilting Irish brogue, “Och, aye, forgive me, sir. I could not help but notice . . .” He swallowed hard.

“What is it, young fellow?” The accent of Van Dorn’s Dublin childhood was almost too faint to be heard over the harder layers of his Chicago years.

“Begod, sir, if you’re not the spitting image of me old dad.”

“Your father?”

“Is it not as if he rose from his grave to parade big as life down Broadway?” He caught himself. “Oye, I mean no harm.”

“No, no, no. Not to worry, young fellow.”

“The splendid whiskers—scarlet as new dawn—the piercing eyes, the high brow.” He shook his head in amazement and in sorrow.

“When did he leave us?” Van Dorn asked gently.

“Only at Easter. I thought I had reckoned with it, and there you were. You’re kind to stop, sir. Don’t be putting yourself out a moment longer.” The young man bowed, his expression still troubled, and turned away.

Joseph Van Dorn was a sharp detective and a shrewd businessman, but he was a kindly soul and he called after him, “I experienced the like when mine passed. I’ll not promise it gets easier, but gradually, you won’t dwell every day.”

“I will cherish that thought . . . You’ve been very kind— Sir, it would give me great pleasure to stand you to a wee dram.”

Van Dorn hesitated. He was already late to meet Isaac Bell, but the young fellow looked to be in desperate need, and a brother Irishman in need was not to be ignored. “Of course.”

“There’s a friendly snug just around the corner,” said the redhead, extending his hand. “Finnerty. Jack Finnerty.”

They shook hands and found the bar. The bartender greeted Finnerty with a warm “Welcome back” and poured Bushmills.

Van Dorn waited a decent interval to let Finnerty speak about his father before, in hopes of changing the subject to one less morbid, he asked, “What line are you in, Mr. Finnerty?”

“Coal,” said Finnerty. “Or, I should say, supercoal.”

“What is supercoal?”

“Something of a modern miracle. Scientists have developed a means of releasing the excess power hidden inside coal—burning a bucket of supercoal produces the heat of a carload. Imagine a locomotive crossing the continent on one full tender, or the city dweller snug in his apartment with his entire winter supply in a single cupboard.”

“I have never heard of it.”

“You’ll be hearing of it soon—”

All of a sudden, Finnerty jerked his watch chain and looked at the time. “Begor! I must run. I promised the investors I’d attend their board meeting. I’ve not ten minutes to get to Wall Street. Thanks be to God for the El—though they’ll not finish digging the Rapid Transit Subway soon enough for me. What good fortune to meet you, Mr. Van Dorn! You were kind when kindnesses made a difference.”

Van Dorn shook his hand and held tight a moment to ask, “At what stage of development is this invention?”
