Why press the old proprietor into service, when a word to the Commandant of Berlin would have brought sentinels galore?

Because Count Udo von Wedell, head of the German Secret Service, occasionally unloads a uniformed stenographer on an unsuspecting, but suspected, visitor to Berlin; and, Udo failing, Captain von Tappken, his right-hand man, might be tempted to do so. Spy mistrusts spy, you know.

On his part the War Lord was as anxious to keep his conference with Bülow from Franz, as Este was to invent excuses for wishing a night free from social duties or official business. Accordingly Wilhelm had twice changed the programme.

His first idea was to receive Bülow at the Schloss. No; Franz might hear of it. His valet (Father Bauer) was singularly well supplied with money, and royal lackeys (confound them!) prefer _trinkgeld_ to medals, even.

Already vague hints at an incognito royal visitor had appeared in one or two gutter journals.

"Augustus tells me that Frederick Leopold had his Berlin house thoroughly overhauled. Nothing unusual about inspecting the renovated lair of the Prussian Croesus?" suggested Prince Phili Eulenburg. He referred, of course, to the Grand Master of Ceremony and the Lord of Klein-Glenicke, the War Lord’s cousin and brother-in-law.

"By Jove, you are almost too smart for an ambassador, Phili," cried Majesty; "you deserve a wider field, the Wilhelmstrasse or the Governorship of Klein-Popo should be yours. Meanwhile, and until one of those posts becomes vacant, ’phone Bülow to meet me in Leopold’s library at nine sharp. Moltke shall send six men of the First Guards to investigate garden and all, and they will remain for corridor duty. Augustus, of course, must communicate with Leopold’s _maître d’hôtel_."

At 8.55 P.M. the War Lord, in mufti, fur collar of his great-coat hugging the tops of his ears, slipped down the secret staircase leading from his apartments to a side door, and into Count von Wedell’s quiet coupé. The Secret Service man who acted as groom had mapped out a circuitous route, avoiding the Linden and Charlottenstrasse.
