Van Dorn nodded. “I want you to take over the case as chief investigator.”

Bell threw down a card, picked up the card that Danzler dealt, and slipped it in the fan, which he held in his left hand.

“Are you a lefty, Mr. Bell?” asked Danzler out of curiosity.

“No. Actually, I’m right-handed.”

Van Dorn laughed softly. “Isaac can draw the derringer he hides in his hat, cock it, and pull the trigger faster than you can blink.”

Danzler’s respect for Bell grew during the conversation. He drew back his coat and revealed a 1903 Colt .38 caliber hammerless automatic. “I’ll take Joe’s word for it, but it would be interesting to put it to the test—” Danzler had not finished the sentence when he found himself staring into the twin muzzles of a derringer.

“Age has slowed you, Henry,” said Van Dorn. “Either that or your mind wandered.”

“I have to admit, he is very fast,” Danzler said, visibly impressed.

“What office will I work out of?” Bell asked Van Dorn as he slipped the derringer back in his hat, where it fit in a small pocket inside the crown.

“The crimes have occurred from Placerville, California, in the west, to Terlingua, Texas, to the east,” replied Van Dorn. “And from Bisbee, Arizona, in the south, to Bozeman, Montana, in the north. I think it best if you operated in the center.”

“That would be Denver.”

Van Dorn nodded. “As you know, we have an office there with six experienced agents.”

“I’ve worked with two of them three years ago,” said Bell. “Curtis and Irvine are good men.”

“Yes, I forgot,” Van Dorn said, now recalling. “I might add, Colonel, that Isaac was responsible for the apprehension of Jack Ketchum, who was later hung for two murders committed during a train robbery.” He paused and reached under the table and produced an identical valise to the one Bell had carried into the gambling salon. Bell then passed his empty valise to Van Dorn. “Inside, you will find the reports on all the crimes. Every lead so far has led up a blind alley.”

“When do I start?”

“At the next landing, which is Clarksville, you will depart and take the first train to Independence. From there, you will be given a ticket on the Union Pacific express to Denver. You can digest and study what little clues and evidence we’ve gathered.

Once you arrive, you’ll take up the hunt for the murdering scum.” A look of anger and frustration clouded Van Dorn’s brown eyes. “Sorry, I didn’t give you a chance to pack when you left Chicago, but I wanted you to start as soon as possible.”

“Not to worry, sir,” Bell said with a faint smile. “Fortunately, I packed two suitcases for the duration.”

Van Dorn’s eyebrows raised. “You knew?”

“Let’s say I made an educated guess.”

“Keep us informed on your manhunt,” said Danzler. “If you need any help from the government, I’ll do all in my power to assist you.”
