Molybdenum Forcing Pass System:
S ---- N
P --- 1♣ (1♠) (opening hand, 0-bad 12)
1NT --- 4♦ (15-18 balanced, texas transfer)
4♥ --- P (completed transfer)

By the way, without the ♣A in North's hand the bidding goes:

P --- 1♦ (1♠) (opening hand, 0-5 with 5 ♥ OR slam oriented with at least 5 ♥)
2♥ --- P (or 3♥) (3+ hearts)

[CamHenry]

1♦-1♠ 16+, excluding GF/8+ (almost) any
1N-2♦ 16-19 bal/transfer ♥
2♥-3♥ denies 4-card support/6+ ♥, mild slam try (some negative inferences available)
4♥ No particular slam interest if partner can't bid anything stronger than 3♥

If E doubles 1♠, the auction could continue the same way. The alternative is that S passes, showing a balanced 16-19 without a ♠ stop, but I think Q9xx is safe enough. In that latter case, N ends up playing 4♥ on a similar sequence.
