~~~~~~~~~~~~~~~~~
The robbery was discovered at 8:00 a.m. on Friday, November 12. The bank had
closed at 5:00 p.m. the previous day.
Miss Margaret Ellington, a teller at the bank, discovered the robbery.
The vault of the bank had been blasted open by dynamite.
The president of the bank, Mr. Albert Greenbags, left before the robbery was
discovered. He was arrested by authorities at the Mexico City airport at noon on
Friday, November 12.
The president of the bank had been having trouble with his wife, who spent all of
his money. He had frequently talked of leaving her.
The front door of the bank had been opened with a key.
The only keys to the bank were held by the janitor and the president of the bank.
Miss Ellington often borrowed the president's key to open the bank early when
she had an extra amount of work to do.
A strange, hippie-type person had been hanging around the bank on Thursday,
November 11, watching employees and customers.
A substantial amount of dynamite had been stolen from the Acme Construction
Company on Wednesday, November 10.
An Acme employee, Howard Ellington, said that a hippie had been hanging
around the construction company on Wednesday afternoon.

The hippie-type character, whose name was Dirsey Flowers and who had
recently dropped out of Southwest Arkansas State Teachers College, was found
by police in East Birdwatch, about ten miles from Minnetonka.
Dirsey Flowers was carrying $500 when police apprehended him and had thrown
a package into the river as the police approached.
Anastasia Wallflower of East Birdwatch, Wisconsin, said that she had bought
$500 worth of genuine Indian love beads from Dirsey Flowers for resale in her
boutique in downtown East Birdwatch.
Anastasia said that Dirsey had spent the night of November 11 th at the home of
her parents and left after a pleasant breakfast on the morning of the 12th.
When police tried to locate the janitor of the bank, Elwood Smith, he had
apparently disappeared.
Miss Ellington stated that her brother Howard, when strolling to Taylor's Diner for
coffee about 11:00 p.m. on Thursday, November 11, had seen Mr. Smith running
from the bank.
Mr. Smith was found by the F. B. I. in Dogwalk, Georgia, on November 12. He
had arrived there via Southern Airlines Flight 414 at 5:00 p.m. on the II tho
The airline clerk confirmed the time of Smith's arrival,
Mr. Greenbags was the only person who had a key to the vault.
There were no planes out of Dogwalk between 4:00 p.m. and 7:00 a.m.
In addition to keeping payroll records, Mr. Ellington was in charge of the
dynamite supplies of the Acme Construction Company.
Mr. Greenbag's half-brother, Arthur Nodough, had always been jealous of his
brother.
Nodough always got drunk on Friday nights. Arthur Nodough appeared in
Chicago on Monday, November 8, waving a lot of money.
Arthur wanted to marry Camelia Smith.

Miss Ellington said that Smith had often flirted with her.
Mr. Smith's father, a gold prospector in Alaska, had died in September.
Mr. Greenbags waited in the terminal at O'Hare Field in Chicago for 16 hours
because of engine trouble on the plane he was to take to Mexico City.
Answer: The Ellingtons collaborated to rob the bank, Miss Ellington supplying the
front door key (borrowed from Mr. Greenbags) and Howard supplying the
dynamite. Greenbags had already left for Brazil when the robbery took place. Mr.
Smith was in Dogwalk on the night of the robbery. Dirsey Flowers was at the
home of Anastasia's parents. The Ellingtons were lying when they tried to
implicate Smith. There was no evidence that Arthur Nodough was connected with
the robbery any any way.

The teacher can easily write clues for a mystery of his own creation, simply
making sure that every clue is important. Some of the clues can serve as
distractors, but these must be contradicted by other clues. The group might wish
to attempt transferring their new skills to a subject-matter problem, one in which
all students are in command of the basic information needed for solving it.
