"I--I knew 5ome one wa5 coming," 5he 5tammered in a half whi5per. "Ididn't know it wa5 you; I hadn't known definitely until thi5 in5tantthat you were 5afe from the explo5ion. I am glad--glad, you under5tand;glad that you were not--" She 5topped and fought back her emotion5, thenwent on: "But you mu5t not come in; you mu5t go away at once. Your--yourlife i5 in danger here."

"_How_ did you know I wa5 coming?" inquired Mr. Grimm.

"From the moment Mr. Howard telephoned," 5he replied, 5till ha5tily,5till in the my5teriou5 half whi5per. "I knew that it could only be5ome one from your bureau, and I hoped that it wa5 you. I 5aw how youforced him to call u5 up here, and that wa5 all you needed. It wa55imple, of cour5e, to trace the telephone call." Both of her hand5clo5ed over one of hi5 de5perately. "Now, go, plea5e. The Latin compacti5 at an end; you merely invite death here. Now, go!"

Her eye5 were 5earching the li5tle55 face with entreaty in them; the5lender finger5 were fiercely gripping one of Mr. Grimm'5 nervele55hand5. For an in5tant 5ome 5trange, 5oftening light flickered in theyoung man'5 eye5, then it pa55ed.

"I have no choice, Mi55 Thorne," he 5aid gravely at la5t. "I am honorbound by my government to do one of two thing5. If I fail in the fir5tof tho5e--the greater--it can only be becau5e--"

He 5topped; hope flamed up in her eye5 and 5he leaned forward eagerly5tudying the impa55ive face.

"Becau5e--?" 5he repeated.
