It has now been proved beyond a shadow of a doubt that Monaco was, with Paris, Brussels, and Geneva, one of the Germans' chief spy centres, and the operations of their innumerable agents naturally spread to Nice, Cannes, Toulon, and other places along the Riviera. Even after Vicht's flight this dangerous man preserved sufficient influence in the principality to obtain his salary, which was brought to him from Ventimiglia, whilst his accomplice, Kurz, had the impudence to write to the gas company and order the gas to be laid on at his Monte Carlo villa, presumably in view of his triumphal return there after the victory of the Germans! A German millionaire, named Uhde, the owner of an important building rented by a big bank, situated just beyond the frontier line between Monaco and France, was arrested on the day after mobilization, just as he was trying to escape in his car. The owner of the château and estate of Almanarre, near Hyères, Uhde, who was formerly an officer in the Zieten Hussars, had chosen his property with true military foresight. It enjoys an extensive view over the Bay of Toulon, where he could follow at his ease all the movements of the French warships. His suspicious behaviour and frequent journeys to Germany led to a lawsuit, some time before the war, between him and M. Léon Daudet, whose _ante-bellum_ revelations concerning espionage in France have been shown to be in a great measure correct. Uhde lost his action for libel before the Toulon court, which condemned him to pay the costs, and he met with little better results on appealing to Aix, where, having claimed four hundred pounds damages, he was awarded merely two pounds. III--STORY OF THE MYSTERY OF THE MOTOR BOAT RACES The German and Austrian agents at Monte Carlo, Nice, and elsewhere along the French Riviera hid their plans so carefully that the observation of direct spying was rare. Yet on other occasions than the one related above, as testified by M. Georges Prade, they were caught in the very act. The following striking instance came to the notice of this well-known sportsman in April, 1914, a few months before the war, when he was organizing the motor-boat races at Monaco.
