This was our bidding. The opening was 15-17. The double was penalty, showing a hand that held a good suit and was likely to beat 1N if on lead. 2H was transfer.
2N was meant as minor takeout, which partner read correctly. The trouble began now, as I was afraid, without discussion, that 4H might be construed as a heart/club 6/4 or 5/5 hand. Knowing all finesses were on, I was concerned that partner wouldn't be able to reach his hand often enough to take 2 finesses even if he had a singleton spade.
Could you have done better? His hand:
