destination.

On arrival at Milan, I kept observation upon him. From the chief
telegraph office he dispatched a telegram and then drove to the Hotel
Cavour, where he engaged a room. At once I telegraphed to Madame to
bring Lola and join me at the Hotel de Milan. They arrived next day
and I told them of my movements.

Three days later Zuccari left the Cavour and traveled to the frontier,
little dreaming that he was being so closely followed. Madame and Lola
went by the same train, but having discovered that he had bought a
ticket for Zurich, I left by the train that followed.

On arrival at Zurich, I was not long in rejoining my companions, for
we had a rendezvous at the Savoy, when I learnt that Zuccari was
staying at the Dolder Hotel, up on the Zurichberg above the Lake.

"A man named Hauser is calling upon him this evening," Madame told me.
"We must watch."

This we did. More respectably dressed than when in Naples, I was

Hence I took courage and, later on, engaging a room, moved to the same
hotel. Next morning I saw the banker meet the man Hauser a second
time, and together they took a long walk on the outskirts of the town
above the Lake.

From the concierge I extracted certain valuable information in
exchange for the hundred-franc note I slipped into his hands. It
seemed that the banker Zuccari frequently visited that hotel, and on
every occasion the man Hauser came to Zurich to see him.

"They are conducting some crooked business--that is my belief,
m'sieur!" the uniformed man told me in confidence.

"Why do you suspect that?" I asked quickly.

"Well," he said confidentially, "Isler, the commissary of police, who
is now at Berne, once pointed him out to me and said he was a friend,
and believed to be one of the acco
