Has anybody sussed which way round the clue 10/15 is supposed to be. The clue is Bird's eggs found on sideboard? 5/4, and yet 10 is only 4 letters and 15 is 5. The letters I have are R _ O _ / S _ A _ N or if it is the other way round this will be S _ A _ N / R _ O _. it's my last clue and I'm stymied. Thanks
