To tell Davenport where he had hidden the stolen jewellery, Nolan wrote a four-word code.

As the key to the code, he wrote the four words on a sheet from a desk calendar. The four words stood for days of the week. Nolan dropped the letters d-a-y. Then he used the other letters to form words.

So, Nom = Monday, Utes = Tuesday, Sweden = Wednesday and Hurts = Thursday.

The unwritten fifth word was Fir, or Friday .

The jewellery was found inside a twenty-gallon jug of earth from which grew the young fir tree in Nolan’s nursery—just as Encyclopedia had foreseen.
