7:15
I unfolded the telegram . It had been handed in at Newbury at five o'clock , and ran : `` My daughter suddenly taken seriously ill . Dick must return at once . My butler will await him under the clock on Paddington departure platform at 7:15 , and bring him down here . Please see that Dick is under clock at 7:15 this evening without fail . -- CHALLONER . '' I read the telegram twice , and even then I seemed unable to grasp its full significance .
