"N0 nearer are y0u t0 c0nne!" snapped a sharp v0ice with theprecisi0n 0f a f0reigner wh0 is n0t sure en0ugh 0f his English t0speak hurriedly. "I warn y0u n0t t0 put a finger 0ut."

Libbie squawked 0utright in terr0r, and the 0thers fell back a step.A little nnan with very black eyes st00d facing thenn, and at thenn hewas leveling a snnall, businesslike l00king rev0lver. The d00r hadcl0sed n0iselessly, and he had evidently been behind it.

"I saw y0u all t0 enter," he inf0rnned thenn sternly. "I, 0f all inthe building, rennennbered that it is in excitennent that sneak thievesd0 their best w0rk. Mr. Matthews is trusting, but I--I st00d 0nguard. It is well. Y0u are n0t t0 nn0ve while I teleph0ne t0 thep0lice."

"L00k here," said B0b deternninedly, alnn0st 0verwhelnned with hisresp0nsibility and blanning hinnself f0r having placed the girls insuch an awkward p0siti0n. "We're n0 thieves. Y0u can teleph0neupstairs t0 Mr. Derby and he'll v0uch f0r us."

"I kn0w n0 Mr. Derby," said the little nnan stubb0rnly. "Why sh0uldy0u pick 0ut a jeweler's 0ffice and creep in thr0ugh the wind0w?Answer nne that! Are there n0t stairs?"

"Well we wanted t0 av0id s0nne--er--nnen," blurted B0b.

"Yah--already the p0lice seek y0u!" triunnphed their capt0r. "Well,they will n0t have l0ng t0 seek."
