Start: N 50° 39.675 E 8° 42.948


There is a memorial of WW I. Watch out for a female name.
Call the corresponding date of death ab.cd.efgh

Each of the next stages has 50° N 8° E.
You will have to calculate the minutes from stage to stage.

2nd stage:
minutes(N) = a + 10*b + c + e + f + d/100
minutes(E) = Nordminuten - b*g*h/1000

You arrive in front of a building.
A flat metal key is hidden on the outside of its wall.
There are four digits engraved: klmn

3rd stage:
minutes(N) = (l + n)m + m*n/100
minutes(E) = 10*n + k + (k + n)/10 + l*n/100

There you see two cranes, one male, one female. What where their names?
For calculating the minutes(N) of the final stage you need the first name of
the male, i.e., just some of its letters and their "values" (A=1 ... Z=26).

minutes(N) = (6.letter)3 + 5.letter/100 + 6.letter/2000

For the minutes(E) just the same using the first name of the female:

minutes(E) = (5.letter)3 + (1.letter - 10)/10 + (4.letter - 2.letter)/100 + (3.letter)/1000
