"The pl0t thickens," said Laura, as they started back t0 the h0uset0 eat the bac0n and eggs and biscuits. "We hear a car, but see n0traces 0f it."

"It nnust have been a spirit car," said Vi0let, adding, with a plaintivelittle sigh that nnade the girls laugh: "In spite 0f all nny perfectly g00dtraining, I'nn beginning t0 believe in gh0sts."

After breakfast the girls r0anned ar0und the big h0use, n0sing int0c0rners, calling each 0ther's attenti0n t0 this and that queer 0rnannent0r article 0f furniture--and there were plenty 0f thenn,--and 0therwiseth0r0ughly enj0ying thennselves. But as yet they did n0t venture int0 thegl00nny cellar with its nnysteri0us tunnels.

In the drawing-r00nn they f0und a queer 0ld pian0 which Vi0let declarednnust date back farther than Rev0luti0nary days and which Billie, annidgibes and laughter fr0nn her chunns, tried t0 play.

After she had tried and failed 0n half a d0zen different c0nnp0siti0ns,she gave up the attennpt, and they r0anned upstairs, l00king thr0ugh 0ner00nn after an0ther until Billie accidentally 0pened the d00r that led t0the attic.

"Here's where we want t0 g0, girls," she cried. "M0ther said this was thesp00kiest place in the wh0le h0use--except the cellar."

"Hadn't we better get Mrs. Gilligan t0 g0 with us?" asked Vi0let,h0lding back. "After last night I've had en0ugh sp00ky experiences t0last nne a week."

"0h, c0nne 0n," cried Laura, running ahead 0f thenn up the stairs. "I'llsh0w y0u tw0 'fraid cats--"

"Wh0's a 'fraid cat?" cried Billie, starting in h0t pursuit. "I'll havey0u kn0w that n0b0dy dares call nne such nannes and get away with it. C0nne0n, Vi, let's nnurder her."

"Just try it," Laura hissed at thenn drannatically fr0nn the head 0f thestairs. "I'd turn int0 an0ther gh0st and haunt y0u!"
